Nvidia’s latest graphics cards and chips throw down the gauntlet to Intel and AMD. Go behind the scenes with this guide to the big technologies including PhysX, CUDA, and games like Far Cry 2 and S.T.A.L.K.E.R Clear Sky.

First GPU in GeForce 9 range unveiled.

GPUs 'not just for gaming and movies'.

When we think of SiS graphics, we usually think of low cost, low-end cards or integrated offerings for the entry-level 2D market, with the possibility of some rudimentary 3D capabilities thrown in.

A competent card with older games, but it can’t handle the new generation of games.

There is only one card in this picture. No, really. Okay, let’s discuss this.

New drivers introduce CrossFireX for Windows Vista and ATI Hybrid Graphics support for Windows Vista.

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

Quadrupled graphics performance with ATI CrossFireX.

An exciting glimpse at future performance, but by the time games appear to make them worth buying, the price will have plummeted.

Potentially Much faster than a X1900 XTX in games with large textures yet it costs the same. At over $100 less than Nvidia’s 7950 GX2, it’s a fine card.

Performance, software and value that almost snatches away the A-List crown.

Both AMD and Nvidia are now shipping chipsets with hybrid graphics. So what is it, and is it a good idea for games? See what our tests revealed.

Tesla GPUs aimed at geoscience, molecular biology and medical diagnostics.

'Fundamental new architecture' promises major speed boost.

Breathe some life into your old PC in time for a Vista upgrade with these budget AGP video cards.

ATI has a new weapon in the battle for the title of kingpin-of-all-game-graphics - it's the 7xx series.

An interesting concept But performance is determined by drivers and ultimately it smacks of gimmick.

2D graphics speed has been a non-issue for some years, and the demand for analog image quality is also waning in the move to digital TFTs, all of which means that Matrox's reputation for analog engineering is now a moot point for most users.

A useful card for more relaxed gaming, and a quiet cooler to boot.
