Lets see, on my system with a 6600Gt at 596mhz/1044mhz with stock cooling, and my cpu at 2366mhz with a 205mhz fsb (loose timings) I got 3789.
At 2228mhz with a 222mhz fsb I got 3657. (same timings)
At the same speed but with a memory divider to run the memory at half speed with extremely aggressive timings, I got 3576, but the cpu score dipped to around 2900, wheres it was around 3700 for the previous test. Hmm, if the 3d and cpu scores are anything to go by, my video card and cpu are well matched. Bah, I could still benefit from a better video card, but I'll wait till DDR2 athlon 64s to make a complete overhall of mym system.
What's the top scoring video card in 3dmark right now? I'd like to have at least 2x-3x the performance of my 6600gt when I upgrade.
