GeForce 6600 Preview Info Review
Posted on by LSDsmurf
Note that both versions are on PCI-Express, while the 6600GT is SLi Enabled, meaning you can run two cards in one machine for added performance. Shader Model 3.0 features on both cards of course, NVIDIA continuing to hold that over ATI. Interestingly, both cards are listed as 128-bit memory interface, while previous rumours have had them as 256-bit.
