"Today we are looking at a pair of NVIDIA's new 9800 GX2 graphics cards in quad SLI mode. Running together you have a pair of the fastest graphics cards around.

In all whether or not quad SLI would benefit you depends on what you want to do. If Crysis is your game, then Quad SLI is just what you need to get playable frame rates at very high settings. However if benchmarks are what you want to run Quad SLI might not be for you."
