Notes

In order to test the impact video memory size has on performance, we underclocked a GeForce 7900 GTX board to GeForce 7900 GT levels. It’s not quite the same as having a real GeForce 7900 GT 512MB, but it’s close. We also ran benchmarks with ATI’s recently released Radeon X1900 XT 256MB, comparing it to a 512MB XT board. Keep in mind that these ATI cards were tested on the P5N32-SLI SE platform, although performance of the 512MB XT board is pretty similar to the numbers we saw with the P5W DH Deluxe.
