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

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

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

The graphics market is a cutthroat game, and we have seen many casualties recently. Not all of them have been fatal, like Matrox, which has recently backed out of the consumer race, or Rendition, whic

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.

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.

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 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.

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.

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.
