GPU support and Nvidia SLI

Question

It would appear that even with Nvidia's new Vista drivers 178.24 (today Oct 15) you will only get GPU support if you turn off SLI. Seems like a waste of a second video card. Hopefully Nvidia will get this sorted in the next release.
My system:
Intel QX6888 (quad core)
3 GM RAM
2x GeForce 8800 GTX (normally in SLI)
Vista 32bit

Answer 1

Read the fineprint and don't listen to the marketing fluff. NVidia never has made any promises that it would double the available texture resolution nor double the number of polygons a 3D program could display or any other real feature relevant for the performance as perceived by the user. All it does is extend your desktop resolution or improve a few things on the texture filtering and antialiasing by providing different cooperative methods of the two GPU working on the same problem at once, but even a quad SLI can not override the rules of OpenGL or any other display API else for that matter. There is really very little measurable benefit to SLI in combination with professional apps, even for the always resource hungry CAD people, and I don't exactly call paying twice the money for a meagre 5 - 20% gain a good deal. This may be different for others, but point in case: SLI has no place with most current commercial mainstream apps and unless NVidia open up the API so others can really understand and use what SLI does, this will not change in the foreseeable future.
