A belated thanks for the review.
Regarding the benchmarks, it's not just the Quake 4 numbers for 8600 GTS that seem out of whack. The 8800 GTS FPS dropped in both Quake 4 and UT3. I know you guys have changed your platform slightly, but it seems the only difference is a
faster processor.
I have an EVGA 8800 GTS 512 I got for $300. I'm seriously considering step-up, but still have about 18 days left so I'm hoping the price drops a bit on their website (currently it's $350) before I have to act. You do have to factor in ~$7 shipping from them (if you waive the signature confirmation) and shipping the old card to them, so for me it'll add up to almost $65 for the upgrade. They clock their GTS at 670 GPU, so the memory is where the real difference will be with stock specs. But I'm sure the GTX will have plenty more overclocking headroom (my GTS struggles at around 740-750 unless I really crank the fan up).
Also keep in mind that you get the option to do tri-SLI in the future (who knows? If I can pick up a couple for cheap once Vista's woes are sorted out, Crysis on Very High becomes a possibility--I game on a 22" at 1680 x 1050). Not to mention Hybridpower once those chipsets come out (who said you can't be indulgent and environmentally conscious at the same time?
)
And don't forget that the 9-series will soon be the primary focus of Nvidia's driver releases, so the performance gap between 8800 GTS and 9800 GTX may widen with newer games.
If I didn't have the Step-up option, I wouldn't pay $330 for a 9800GTX now that the 8800 GTS can be had for about $220 AR, but I'm sure those GTX prices will come down in a couple of weeks, at least on Newegg and such.
