To test SLI performance, I turned to my faithful Athlon 64 4800+ dual-core CPU and Asus A8N-SLI Deluxe motherboard. Believe it or not, but this system has been running on a Windows XP install that was done well over a year ago. As expected, setting up a mixed-vendor SLI configuration was just like setting up a normal SLI configuration.

In my excitement to find out how this configuration would perform, I forgot to power the graphics cards and was immediately greeted with the following reminder upon rebooting into Windows.

The following results are from Doom 3 and F.E.A.R. with the GeForce 7900 GS running in SLI. Increases in performance up to 83% were realized over the single GPU benchmark results on the previous page.

CONCLUSION
The GeForce 7900 GS is an example of NVIDIA's commitment to the gamer who is looking for performance and features at a mainstream price. At $199.00, the GeForce 7900 GS provides a level of performance that until now has never been attained in this price range.
Put two of them together and experience the ease of set-up and usability of SLI along with performance that will be able to handle today's demanding games. With the GeForce 7900 GS, NVIDIA has delivered the most bang, boogie, and bling for the buck to the demanding gamer right now. We would like to thank Ryan Dumas from XFX and Joe Darwin from EVGA for providing us with their fantastic graphics cards.
