Q3, CoD, UT2003
A few bandwidth tests coming up. UT2003 is run at 800x600, and the benchmarks tracks a bot match inside the Sun Temple arena. At such a low resolution and enclosed space the test becomes system limited. In this case, the system is limited to 'only' 190FPS average.
It's more than competitive against two nForce3 250 rivals in the bandwidth test that masquerades as Quake III.
Call of Duty is run with sound enabled. Different audio systems place varying load on the CPU. It transpires that CMI's CODEC and AC'97 make a decent combination, at least as far as performance is concerned. We don't really get excited about the difference when the average is well over 100FPS on all three counts.
