NVIDIA is one of the top motherboard chipset companies in the world today, dominating the AMD Athlon high-end market at the moment. In a recent Valve survey, 98.8% of multiple GPU users used NVIDIA SLI chipsets, an amazing figure by any stretch of the imagination.
SLI works well for those wanting the absolute best performance in games today, especially when NVIDIA 7950GX2 cards are utilized in SLI ("Quad-SLI) or two 7900GTXs are used in SLI mode.

When I go into the review of this chipsets I'll cover them more completely.
