Keep Laptop in Good Condition
1. Do not ever put a heavy burden on the laptop if we put the goods that have a heavy burden on the laptop, it can cause scratches on the LCD screen.
2. Avoid placing the laptop inside the bag with items that are too full of stuff .. because it will cause pressure on the laptop
3. note the temperature condition
Laptop or notebook is composed of various electronic components whose performance is affected by temperature. Among other things, the temperature is too extreme, such as too hot or too cold, can disturb the performance or even damage the laptop. Therefore, avoid the habit of leaving the laptop in the carwhich was parked under the hot sun. Avoid also highlight the laptop is under direct sunlight. Generally, manufacturers recommend a temperature between 5-35 degrees Celsius. Meanwhile, to the height recommended laptop to work at an altitude below 2,500 meters above sea level.
4. Storage
If you will keep your laptop in a long time (one week more), should remove the battery and store in a cool, dry, and circulate air well enough. Place the silicone gel to prevent mildew. So want to use it again, stun or content of the battery byfilling and emptying as many as three times in a row.
5. Avoid magnetic fields
To protect the existing data on the hard disk, do not place devices that contain magnetic fields / strong electromagnets around a laptop. From these devicesproducing magnetic fields, such as speakers are not shielded (unshielded speaker system) or cellular telephone. If you want to access the Internet using the facility infrared on the phone, put the phone in the distance about 15 cm from the laptop.
6. Use stabilizer
If you are working on a laptop with the use of electricity (without batteries), then you should use a stabilizer that can prevent the occurrence of an unstable electrical voltage to your laptop.
7. Deadly correctly
Never turn off the laptop while the hard drive indicator light is still blinking. This indicates the hard disk is still active. The loss of power suddenly (eg when the laptop is turned off) can cause data loss or interruption of performance on the hard disk. Make sure the hard drive light was switched off before you shutdown the laptop.
8. Avoid too soft surface
Do not place the laptop when the lights in place with a surface that is too soft as a sofa or mattress, so the laptop to be seen rather drown. This is very dangerous, because it can inhibit the release of heat from the laptop and make the laptop overheating.
9. Hinges monitor
If observed closely, in the folds between the CPU and the LCD monitor there is a hinge that allows the two components were clenched to each other. Be aware that the heaviest burden in a laptop is in partthese hinges. Therefore, do not give a snap when opening the monitor when going to activate the laptop. Vice versa, do not be too hard to close the monitor when finished using the portable computer.
10. Do not disassemble the laptop.
Dismantle their own laptops or not by experts, is a very unwise action. Laptops are not like ordinary radio or tape recorder. Many parts of the very small of the manufacturer have been assembled using robotic precision. If you're careless, then your laptop could be damaged severely. Always carry a defective laptop to the IT or the service center of your laptop.
That's 10 tips for caring for laptops are always in good condition
Step by Step Fix Regedit
Generally we click the program icon in the start menu or on the desktop to run certain programs. But the utility programs are not all available in the start menu or the desktop. These programs (such as Regedit.exe, cmd.exe) usually run through the Start menu> Run. What can we do if there is no Run menu in the start menu?
a. Utilizing Windows Explorer
Run the Windows Explorer, locate the file you want running the program in the folder C: \ Windows, or in C: \ Windows \ System, or in C: \ Windows \ System32. Then double-click on the file program.
b. Utilizing the Command Prompt (cmd.exe)
= Click Start> Programs> Accessories> Command Prompt, or run cmd.exe with the first way above.
= Type in the name of the program you want running, then press enter.
C: \ Documents and Settings \ mr. orche!> REGEDIT
c. Using Batch Files
= Run Notepad through the start menu or through Windows Explorer.= Type in the name of the program who want to run, for example, "regedit" (without quotation marks).= Save the file using the extension. Bat, for example, "TES.BAT".= Run the file. Bat it through Windows Explorer (double click).
d. Using Task Manager (taskmgr.exe) (Windows XP)
= Press Ctrl Alt Del.= Click button [New Task ...] on the Applications tab.= Type in the name of the program, and press enter.
e. Browser exploit Files in ACDSee
ACDSee = Run from the Start Menu.= Find the file you want running the program in the file browser window.= Double-click the program file.
2. Alternative ways of Registry Operations
If you can not run regedit, registry operations can still be done with some of the following alternatives:
Alternative 1: Using the command REG
1. Run Command Prompt (cmd.exe).
2. To see a list of key and value, use the REG QUERY command lokasikey.Example:REG QUERY HKLM \ Software \ Microsoft \ Windows \ CurrentVersion \ Policies \ ExplorerREG DELETE HCU \ Software \ Microsoft \ Windows \ CurrentVersion \ Policies \ Explorer
3. Type REG DELETE namakey / V namavalue to remove certain value.
Example:REG DELETE HKLM \ Software \ Microsoft \ Windows \ CurrentVersion \ Policies \ Explorer / V NoRunREG DELETE HKCU \ Software \ Microsoft \ Windows \ CurrentVersion \ Policies \ Explorer / V NoFolderOptions
Note:
= Root name should be abbreviated, HKCR for HKEY_CLASSES_ROOT, HKLM for HKEY_LOCAL_MACHINE, HKEY_CURRENT_USER to HKCU, HKU to HKEY_USERS, and so on.
= For key names that contain spaces, key name enclosed in double quotation marks.
= To find out more about the operating procedures using the REG command, type "REG /?" Without the quotation marks.
Alternative 2: Using files. REG1. Run Notepad and type as the following example:
The new format (WinXP):Windows Registry Editor Version 5.00[HKEY_CURRENT_USER \ Software \ Microsoft \ Windows \ CurrentVersion \ Policies \ Explorer]"NoFolderOptions" = dword: 00000000
Old format (Win9X/NT):REGEDIT4[HKEY_CURRENT_USER \ Software \ Microsoft \ Windows \ CurrentVersion \ Policies \ Explorer]"NoFolderOptions" = dword: 00000000
2. Save the file with the extension. REG, then double click on. Reg file that you saved.
Explanation:
= First line, "Windows Registry Editor Version 5.00" or "REGEDIT4", is a fixed rule to mark the registry file.
= Second line, "[HKEY_CURRENT_USER \ Software \ Microsoft \ Windows \ CurrentVersion \ Policies \ Explorer]" indicates the location of the registry key, where the list value with the value data mentioned below will be stored.
= Third line, "NoFolderOptions" = dword: 00000000, value names and data they want to value them. In this example the mean change / give the data value 0 at the value named "NoFolderOptions".
= File is typed regedit winxp format (new format) or long format (Win9X/NT), both of which can be used for Windows XP, but the old format can only be used for Windows 9X/NT.
Alternative 3: Using a Startup Disk (only valid for Win9x)This method is the most difficult, and perhaps the only effective way to restore the registry when the system is already completely paralyzed.
1. Boot using the Startup Diska. Enter your Win95/98 Startup Disk into the floppy drive.b. Restart (make sure the configuration settings in the BIOS boot sequence pointing to the floppy).
2. Go to the directory (folder) C: \ WindowsA: \> C:C: \> CD WINDOWS
3. Do the export of data from the registry to a file. Reg specific for the desired keyFormat command:REGEDIT / E namakey namafilereg
Example:REGEDIT / E HKEY_CURRENT_USER \ Software \ Microsoft \ Windows \ CurrentVersion \ Policies \ Explorer TES.REG
If the key name contains spaces, use quotation marks:REGEDIT / E "HKEY_CURRENT_USER \ Software \ Microsoft \ Windows \ CurrentVersion \ Policies \ Explorer" TES.REG
3. Reach the Back Menu Folder Options in Windows Explorer
Some viruses need to hide certain files that the user (computer user) is not aware of the virus and% 0mengetikkan following command at C20agar removed the virus more difficult, by creating a hidden file. File hioleh user if the Folder Options settings on the option 'Show hidden files and folders' enabled. Sometimes even this menu be eliminated by the virus to ensure the virus files remain invisible. To hide the Folder Options menu, the easiest and most commonly applied by the virus is to change the registry settings, by inserting the value "NoFolderOptions" is worth 1. To bring back the Folder Options menu, this value should be removed, or changed the value to "0".
= To alter the Folder Options, click the Tools menu> Folder Options in Windows Explorer.
= Value NoFolderOptions the registry are either or both of the following locations:
HKEY_LOCAL_MACHINE \ Software \ Microsoft \ Windows \ CurrentVersion \ Policies \ Explorer
HKEY_CURRENT_USER \ Software \ Microsoft \ Windows \ CurrentVersion \ Policies \ Explorer
Value can be removed by using the REGEDIT program, or by typing the following command in Command Prompt:
REG DELETE HKEY_LOCAL_MACHINE \ Software \ Microsoft \ Windows \ CurrentVersion \ Policies \ Explorer / V NoFolderOptions
REG DELETE HKEY_CURRENT_USER \ Software \ Microsoft \ Windows \ CurrentVersion \ Policies \ Explorer / V NoFolderOptions
4. Reach the Run menu
Delete value "NoRun" or change the value to 0 by using the registry operation (see sample registry operation to raise above the Folder Options menu). Value "NoRun" is in the key:
HKEY_CURRENT_USER \ Software \ Microsoft \ Windows \ CurrentVersion \ Policies \ Explorer
5. Bring up the Find menu
Delete value "NoFind" or change the value to 0 by using the registry operation (see sample registry operation to raise above the Folder Options menu). Value "NoFind is" at the key:
HKEY_CURRENT_USER \ Software \ Microsoft \ Windows \ CurrentVersion \ Policies \ Explorer
6. Enabling REGEDIT
Sometimes it can not be executed because REGEDIT be disabled via registry settings by the virus. To recover, delete the value "DisableRegistryTools" or change the value to 0 by using the Command Prompt (for WinXP), or by creating a file. REG (only for Win9x).
7. Reach the Hidden Files with Command Prompt Change the attributes Through
Hidden files (hidden) can be raised without playing the Folder Options, but by disabling the hidden attribute on the file. Hidden file attributes can only be changed in Windows Explorer if the Folder Options settings allow hidden files displayed. The alternative is to change the attributes of the file via Command Prompt. To list hidden files via Command Prompt, use the command "DIR / AH". Next use the attrib command followed by the parameter attribute to be changed. The following example can be used to disable the hidden attribute, read only, and the system at once, on all files in current directory:
Attrib-r-s-h *.*
8. Finding Files With Command Prompt
a. View a list of files / folders in current folder:
DIR *.*
b. View a list of files / folders that are in the current folder, including file / folder is hidden:
DIR *.* / A "A" stands for "ALL"
c. View a list of files (not including the folder) in the current folder:
DIR *.* / AD "D" stands for "DIRECTORY", "-" means exclusion
d. View a list of folders (not including files) in the current folder:
DIR *.* / AD "D" stands for "DIRECTORY"
e. View a list of files / folders hidden:
DIR *.* / AH "H" stands for "HIDDEN"
f. View a list of files / folders sort by name:
DIR *.* / ON for files and folders, "O" means "ORDER BY", "N" means "NAME"DIR *.* / AD / ON to folders onlyDIR *.* / A-D / ON to file onlyDIR *.* / A-DH / ON for any hidden filesDIR *.* / ADH / ON for any hidden folders
g. View a list of files / folders sort by type (extension)
The trick is similar to sorting by name, only "/ ON" replaced with "/ OE".
h. Viewing file list sort by size
The trick is similar to sorting by name, only "/ ON" replaced with "/ OS".For detailed information about the rules of use DIR command, type "DIR /?" And press enter.
9. Suspected Deadly Process
The definition process is a program that runs in the background (background program), does not have a form because it is not made to interact with the user. Unlike the application program that does look at having to interact with the user. Viruses are usually made in such a way that when the virus is running is not visible at all, he is just a process. File viruses are currently running normally can not be deleted because the process is running. Usually the virus files can only be removed once the process is terminated. List of application programs and processes that are running can be viewed using the Windows Task Manager (taskmgr.exe) simply by pressing the Ctrl Alt Del. After the Windows Task Manager window appears, we can choose the "Applications" to see a list of application programs, or "Processes" to see a list of processes. Another option is "Performance", "Networking", and "Users".To stop the running application program, select the name of the application from the list, then click the "End Task". To stop the processes that are running, select the name of the process then click the "End Process". If Windows Task Manager can not be executed, we still can see and stop the processes that are running from the Command Prompt by calling the program "TASKLIST.EXE" to see the process list, then call the program "TASKKILL.EXE" to stop the process.
Example:TasklistTaskkill / F / IM Notepad.exe / IM MSPAINT.EXETaskkill / F / PID 1230 / PID 1253 / T
Description:The parameter "/ F" which was

Make Windows Faster than Before
If your computer is so slow, maybe it's time to empty the contents of the folder "Prefetch" in the Windows folder on drive "system" of the computer. How do go to "System" (usually on drive C), then
go to the Windows folder to the folder in there called Prefetch. Get listed in this folder, you will find as many prefetch files.
Remove all contents of Prefetch folder (remember, you do not delete the prefetch folder delete, just the content only!).
Then exit and restart your computer. After the computer starts, run Disk Cleanup to hard drive system (drive C),
then restart your computer and its performance will usually be faster than previous

Best Computer Graphics Card
15. Nvidia GTX 295 – £325
14. Nvidia GTX 285 – £249
It was the six-month refresh and die-shrink of Nvidia’s thoroughly impressive, and mightily successful GTX 280 card.
13. AMD Radeon 4870 X2 – £245
12. Nvidia GTX 275 – £165
11. AMD Radeon 4890 – £140
10. Nvidia Geforce GT 430
- Price: £58
- GPU: GF106
- Manufacturing process: 40nm
- Memory: 512MB – 1,024MB GDDR5
The chip is based on a half-height PCB and in the box you’ll find two spare brackets – both half-height too – for plugging into media-centre/lounge PCs.
With another new CPU design to cover this lower-end card, we’re seeing a GPU that, as well as having its PCB halved in size, has been almost halved itself relative to the GTS 450′s GF106, which hit us a month or so back.
We say almost, because it’s actually a little bit less than half the chip of the rather impressive GTS 450. The GF108 has two Streaming Multiprocessors as opposed to the GF106′s four, meaning we get half the number of CUDA cores and texture mapping units at 96 and 16.
This isn’t a hardcore gamer’s card. Rather, it’s a GPU designed to be dropped into small form factor PCs to play high-def video and do as much video encoding and photo editing as you need in your lounge.
In gaming terms, it can trade blows with AMD’s eight-month-old HD 5570; just enough poke to do some light gaming then, but not a hardcore gamer’s card by any means.
9. AMD Radeon HD 5750
- Price: £85
- GPU: Juniper LE
- Manufacturing process: 40nm
- Memory: 512MB – 1,024MB GDDR5
Moreover, DX11 effects, such as Tessellation and Multi-Thread Rendering, require the kind of resource overheads that the 5850 can’t quite manage. with its narrow memory bus and a GPU that pales in comparison to AMD’s other offerings, it
It also faces very stiff competition in the marketplace. At around the same price you can get the measurably more-capable GTS 450 from Nvidia, and for just a few bob more, AMD’s own HD 5770. This makes it perrty hard to justify as an upgrade to an existing, older card that may be in your system.
On the other had, for the casual gamer with a 19″ monitor, the 5850 is just perfect. And the multi-panel functionailty offered by AMD’s EyeFinity technology means that, for multi-screen productivity setups, there’s still a lot to like.
In summary, the 5750 is much more suited to productivity and casual gaming at lower resolutions than full-on gaming. It can manage the job, but for this price, there are much better options open to you.
8. AMD Radeon HD 5770
- Price: £100
- GPU: Juniper XT
- Manufacturing process: 40nm
- Memory: 512MB – 1,024MB GDDR5
Offering competent performance at the mainstream 22-inch resolution of 1680×1050, it also comes with the promise of cool-running, quiet operation – a trademark of AMD’s current design philosophy. However, try and crank the shinier graphical elements – such as Anti-Aliasing and Anisotropic Filtering – too high, and the card starts to run out of grunt.
AMD’s EyeFinity technology, which enables multi-screen scaling, is a very real option with the 5770, though we wouldn’t recommend the 5770 for multi-screen gaming; it just doesn’t have the throughput for gaming at huge resolutions.
But the really interesting thing about the HD 5770 is what its price represents. at these low prices, our thoughts turn to Crossfire setups. For under £200, you can net yourself a twin-card setup which offers kick-ass performance at mid-range resolutions.
If you’re content with that 22-inch monitor and want zingy performance on a budget, this CF setup is probably the cheapest way to achieve it… and at a price equivalent to Nvidia’s last-gen 285, which such a setup will blow out of the water, it’s pretty mouth-watering. Oh, and did we mention the 5770 is DX11 capable? Yum.
And that’s what that lower price-point really represents: the prospect of a twin-card CrossFire setup, and a pretty feisty one at that.
7. Nvidia GeForce GTS 450
- Price: £150
- GPU: GF106
- Manufacturing process: 40nm
- Memory: 1,024MB GDDR5
This tiny powerhouse (well, it’s still dual-width, but pleasingly short) is capable of feats beyond it £90-£100 pricetag. What’s more, in SLI, you’ll see massive performance gains, making the dual-card upgrade path a realistic and impressive option for budget systems.
The basic GeForce GTS 450 is, architecturally, about half of a GeForce 460 with a higher clockspeed and a narrower memory bandwidth. Given that stock versions of the 768MB version of the GeForce GTX 460 are available for just £125, that extra £20 is well spent.
However, the GTS 450 has the advantage over the GTX 460 of being smaller and requiring less power, which makes it a strong candidate for that SLI set-up
It is, however, now pitched directly up against the HD 5750 in pricing terms thanks to the on-going Nvidia/AMD graphics card price wars. And that is a card the GTS 450 happily beats into submission in any benchmark you throw at it.
6. AMD Radeon HD 6850
- Price: £150
- GPU: BARTS XT
- Manufacturing process: 40nm
- Memory: 1,024MB GDDR5
However, sudden cuts have meant that if you shop around, you can find HD 5850s for Around the price of a GTX 460 1GB.
What you get for your money (around £150 on average) is generous midrange performance that can just hold its own when the resolution rises to 1920×1200. apples for apples, it’s almost a dead-ringer for the GTX 460; interestingly, it also removes AMD’s own 5850 from the equation and pushes it into the passe.
Like it’s big brother the 6870, the 6850 boasts a new anti-aliasing mode, termed MorphoLogical Anti-Aliasing, or MLAA for short.
The interesting thing here is that it uses DirectCompute to process the full scene after it has been rendered, to produce results similar to 4x MSAA but faster and at a reduced memory footprint. There have been some improvements to the anistropic filtering engine too to smooth the transition between different levels of detail to reduce the effects of stepping.
A high-tech, midrange card at a decent pricepoint… we expect AMD’s hardware partners to shift a good few of these.
5. Nvidia GeForce GTX 460 1GB
- Price: £140
- GPU: GF104
- Manufacturing process: 40nm
- Memory: 1,024MB GDDR5
The GTX 460′s rejigged GF100 GPU though may sound like Nvidia has just chopped the GTX 480′s chip in half, with only seven streaming multiprocessors (SMs) against the older card’s fourteen, but inside, things have most definitely changed.
These SMs are the units that hold the myriad CUDA cores (previously known as shader processors), special function units (SFUs), texture mapping units (TMUs) and the polymorph engines that contain the all-important tessellation grunt.
The SMs of the GF100 chips contain a maximum of 32 shader cores, four SFUs and four TMUs. In the GTX 460 chip though NVIDIA has squeezed another 16 CUDA cores into each SM and upped the SFU and TMU counts to eight per SM.
Each of these SMs has also had some CPU-like extra multi-threading goodness injected into them in the shape of an extra couple of dispatch units in each of them.
What this means is awesome midrange performance, and respectable performance at resolutions higher than 1680×1050. Pair a couple up for SLI kicks though, and you get a punchy setup that kicks Nvidia’s own GTX 280 into touch.
4. Nvidia GeForce GTX 470
- Price: £200
- GPU: GF102
- Manufacturing process: 40nm
- Memory: 1,280MB GDDR5
Given the larger pricetag of its big brother, the GTX 480, this represents the most affordable high-end Fermi card out there.
Like the rest of the Fermi range, the 470 has seen some nifty price-cuts, which means it can now be had for £200 (we’ve seen it as low as £188 online). This makes the cheapest 470s at just £30 more expensive than the GTX 460 1GB, the new midrange king. That makes it a pretty compelling prospect right now.
In addition, at the native 22-inch resolution of 1,680×1,050, this card is a fair way ahead of the HD 5870. When things get cranked up though, it starts to lose its competitive edge against AMD’s upper-midrange peer.
Indeed, in our World in Conflict benchmark it actually dropped behind. Still, thanks to its Fermi roots, the GTX 470 has still got the tessellation goods and this promises some future-proofing.
Thankfully, production has ramped up nicely, and the early stock-issues that plagued the 470 and 480 are now long past. More cards in stockrooms means lower prices everywhere, so keep an eye on the 470 – it may yet drop some more.
3. AMD Radeon HD 6870
- Price: £200
- GPU: BARTS XT
- Manufacturing process: 40nm
- Memory: 1,280MB GDDR5
As the advance-guard of AMD’s 6000-series, It also brings some new functionality to the party, in the name of HD3D. This is AMD’s passive 3D technology – largely nascent at present – but the card also supports HDMI 1.4a for 3D Blu-Ray displays.
Architecturally, this mainstream card is a cross between the 5830 and 5850. You get the full-fat 32 ROPs as found on the 5850, but with a core configuration of 1,120 stream processor, as found inside the 5830.
The tweaked core operates at a far higher clock rate to either of these predecessors though, cranking along at 900MHz, as opposed to the 750MHz of the 5850 and the 5830′s 800MHz.
In real terms this means that the 6870 is faster than the 5850, but it’s a little slower than the 5870, so don’t assume because it’s one number higher on the title, there’s a huge generation gap. It’s also faster than its closest competition on the Nvidia front, the GTX 460, and impressively, the GTX 470 as well.
For £200, there’s a lot of value here, the HD 6870 brings AMD’s trademark elegance (reduced heat and noise output) to your PC. We’re eagerly awaiting the rest of the 6000 range to see what AMD has up its sleeve this generation.
2. Nvidia GeForce GTX 480
- Price: £320
- GPU: GF100
- Manufacturing process: 40nm
- Memory: 1,536MB GDDR5
The full Graphics Fermi 100 GPU (GF100) is a marvel of graphical architecture, but some of the 512 small processing (CUDA) cores had to be dropped. The GTX 480 then comes with 480 of these cores, but still manages to pack one hell of a punch.
The key for Fermi, and the purported reason for its lengthy delay, was to ensure it had the best possible tessellation performance.
Tessellation is going to be one of the key tasks for future GPUs, the ability to render more detailed geometry rather than simply better, smoother textures, and Nvidia wants to be at the forefront.
The difficulty is that once tessellation becomes that important, and heavily used in modern gaming development, this card may not quite have the grunt. For now though it’s still an incredible piece of engineering.
The minimum aim for the GTX 480 was to beat AMD’s HD 5870 and, it manages that, making it the fastest single-GPU card around. Let’s see if that changes with AMD and Nvidia’s imminent range-refreshes.
1. ATI Radeon HD 5970
- Price: £425
- GPU: Hemlock XT (2 x RV870)
- Manufacturing process: 40nm
- Memory: 2 x 1,024MB GDDR5
AMD has taken the top spot and managed to hold out against the latest Fermi card from Nvidia, the GeForce GTX 480.
This twin-GPU beauty is one big, beefy, powerhouse of a graphics card, capable of spewing out polygons like last night’s bad kebab. And it since its launch, we’ve seen over £100 fall from the price-tag to keep the stock flowing.
It isn’t just two HD 5870s strapped onto one slab of PCB though – there’s definitely nothing simple about fitting two graphics cards into one form factor.
The actual GPUs are slightly slower than a vanilla HD 5870, making them more akin to twin overclocked HD 5850s. This also means that a Crossfire setup sporting two actual HD 5870s will beat this card in a foot race. But this is Crossfire made easy and that’s something that could rarely be said in the past.
Surprisingly, given the power requirements, it doesn’t get quite as hot as the volcanic GTX 480, a card that actually wiped some of our fingerprints during testing. And surprisingly, it’s remarkably stable and happy to be overclocked.
Some would say that overclocking what is already the fastest graphics card in the world is a bit like overkill, but the option is there for the brave. There are concerns over driver support though, given that DX11 launch title, and AMD Game title DiRT 2 didn’t support the multi-GPU HD 5970 until very recently, so like Crossfire in general, it could present compatibility questions going forward.
It’s not as dear as it was, but it’s still pricey, and what that means with both Nvidia and AMD refreshes on the horizon is anyone’s guess. Ours would be: further price cuts. Affordability FTW!
And right now, it’s still the fastest graphics card out there, posting figures with a healthy lead over the closest competitor from Nvidia. Considering that just a couple of generations ago ATI looked to be choking on Nvidia’s dust with the HD 3xxx series of cards, it’s quite incredible that it has managed to take the top spot and hold it against cards coming out almost half a year later.
Hats off to you then HD 5970, you are the fastest graphics card in the world.
