One graphics card not enough? How about three?

Dedicated gamers always on the lookout for better graphics performance now have a new way to improve the look of their favourite titles - three graphics cards linked up.
Video card giant NVIDIA has extended the capabilities of its SLI technology, allowing hardened gamers to use up to three graphics cards inside their PCs.
The technology promises a 2.8x performance boost over a single-card system. According to NVIDIA, a three-card box will give you resolutions of up to 2560 x 1600 at 60 frames per second.
To take advantage of this video processing power, your PC will have to be equipped with an NVIDIA nForce 680 SLI motherboard and three GeForce 8800 GTX or Ultra graphics cards.
This hardware is capable of providing an eye watering 110 gigatexel-per-second texture fill rate. This translates into smooth flowing video images and extremely detailed backgrounds and characters. The cards also undertake antialiasing which involves smoothing the edges of objects by modifying the transparency of certain pixels.
The result, says the company, is a gaming experience that is hard to beat. Whether you're mowing down monsters with a nail gun or plotting the overthrow of a rival country, having this sort of graphics power at your disposal will make the task even more immersive.
