3-Way SLI Technology
The point of 3-Way SLI is easily described: to play today latest PC games at the highest image qualities and resolutions anywhere. NVIDIA likes to talk about how 3-Way SLI will finally enable gaming at “XHD” resolutions at 60 FPS and that it is the best way for “pro gamers” to play games, but in reality all that adds up to is the first point. High resolutions and high image quality settings are what we are after.
While I already mentioned Quad SLI above, NVIDIA is definitely billing this as NOT just another version of Quad SLI. They claim that the Quad SLI solution was difficult to code for and required some extreme R&D on their ends to get games to work but thanks to the way Vista has implemented both DX9 and DX10 that programming for 3-Way systems is a much easier task. Obviously this means that it will be able to perform better on more titles with hopefully less effort from NVIDIA. We shall see only in due time if this proves to be correct.
