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

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

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

We test three of the latest ultra-portable laptops

Evaluating barebones systems is quite different from performance-based testing using benchmarks. As such, we opted to do a feature-based roundup, covering all aspects of the hardware, including but not limited to: build quality, ease of install, and included feature sets.

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.

The Labs team delves into the guts of this month’s motherboards, and points out what you need to know to chose the right one for your needs.

All the power of a desktop PC in a fraction of the space. We put a selection of desktop replacements 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.

Mike Jennings tests a selection of laptops that offer stunning power and fantastic features in a dozen luxurious packages

All the power of a desktop PC in a fraction of the space. We put a selection of desktop replacements to the test.

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

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.
