We put every current model from ATI and NVIDIA through its paces to find out which offers the best performance and value.

The first place to start tweaking is your BIOS. Enter your BIOS by hitting a key combination on system boot (look out for F1, Del etc). A word of warning though, the BIOS is a very powerful tool, but can cause damage if pushed the wrong way.

We know you want to play games, so we've put 18 PCI Express graphics cards under the microscope to see who really does the job the best.

With so many factors to consider, choosing a motherboard can be a bewildering exercise. We put 11 models through their pace to find the ultimate in performance, flexibility and value

If your PC is less of a speed demon and more of a dinosaur then it's time to upgrade your CPU. We put the latest low, mid and high end processors to the test.

All the current chipsets from both the big gaming guns – ATi and Nvidia – tested, reviewed and rated.

Great gaming performance has never been so affordable. We test 22 current cards from Nvidia and ATI to find what works and what doesn't

Speed up your home network with these wireless routers, including faster speeds, better gaming and VoIP handling and automatic security.

A lot has happened since our last graphics card Labs back in September 1999. Back then the nVidia Riva TNT2 Ultra was starting to give 3dfx a hard time, and the Matrox Millennium G400 MAX was showing

The PC Authority Labs team runs about a million benchmarks and looks under the hood of the latest generation of GPUs to find which one's the best.

Internet everywhere, for affordable prices. Dave Stevenson investigates the claims, tests the speeds and delivers a verdict on the best plan for your mobile dollars.

Hard drives used to be the coolest thing - in the olden days, when all home PCs were slow, a hard drive was often a measure of how 'good' your computer was. For quite sometime, however, processor and graphics technology stole the limelight. Hard drives have been taken for granted - an ambient component that accompanies your sparkling graphics card and gi-normous heat sink.

Since the launch of PC Authority magazine 30 issues ago, we have placed an emphasis on the concept of computing in the real world. This means that all the PC hardware that passes through our Labs is t

Turn on and tune in with cards that give your PC a whole new lease of AV life.

To test the TFTs in this month's Labs we relied on a few different methodologies. All TFTs were tested on the same test bench PC consisting of a Gigabyte 8GE667-PRO motherboard and 2.53GHz Intel Pentium 4 processor with 512MB of DDR RAM, running Microsoft Windows XP Professional.

We put six sub-$500 pocketable cameras to the test

Benchmarking PCs is a tricky business. You need to ensure that you stress the systems, but also that the results you get will be relevant in the real world. Previously we have relied heavily on BAPCo's SYSmark2002 for simulating home and office use, with programs such as Excel, Word, Outlook, and web content through Adobe Premiere and Macromedia Dreamweaver. However, due to SYSmark's history of instability as well as the sheer length of time it takes to complete a run, we have put it on the backburner in favour of PCMark04 for this Labs.
