nVidia supports Quad SLI

nVidia SLI technology allows multiple cards to cooperate by splitting the screen real-estate between cards. Until now only two cards have been supported, but now quad SLI can work.

Currently dual GeForce 7950 cards work (as they already have two graphics controllers on board).

Gamers also need a very high spec system as the display must support 2,560 by 1,600 pixels.
