Conclusion
GeForce 7950GX2 in Quad-SLI leaves us with a bad taste in our mouths. The cost is great and the results are less than desired, whether you buy from a system builder or do it yourself with these new beta drivers. The results show that two graphics processors in a single GeForce 7950X2 can beat the four of Quad.
Perhaps it would be wise for Nvidia to delay the WHQL Quad driver a bit longer, until they get better numbers. We hope to have some results with Conroe based systems to see if a boost from the system will help unlock any potential the Quad cards have in them.
For now, Quad-SLI in your system is a status symbol. When a single Radeon X1900XTX or GeForce 7900GTX does as well as each did in the tests, we think Quad is a little too immature, at least for the time being. Perhaps Nvidia was too hasty getting this to market before the kinks could be worked out. ATI seems poised to launch another card shortly, and this foreknowledge casts doubts on what Quad can do. Only time will tell what will happen to Quad SLI, but right now, what I see does not make me feel that I need to have it.
