For our next game test, we benchmarked all of the test systems using a custom multi-player Doom 3 timedemo. We turned the resolution down to 640 x 480, and configured the game to run at its "Low-Quality" graphics setting. Although Doom 3 typically taxes today's high-end Graphics Processors, when it's configured at these minimal IQ settings, it's much more CPU and Memory-bound than anything else.

Benchmarks with Doom 3 OpenGL Gaming Performance

Our Doom 3 tests show that this game engine definitely appreciates the added memory bandwidth of 667MHz DDR2 memory on the P5ND2-SLI Deluxe and the i955X Intel board.  The Asus board takes the lead by a hair but both boards outpace even the Athlon 64 4000+.  The nForce 4 SLI Intel Edition reference board seemed to have some sort of anomaly in testing, however, because it's scores don't scale along with its DDR667 driven counterparts.
