A C2D 6600 is a processor
Anyway, with my single 8800GTS I get 53FPS AVG in TBD-track, when overclocked, about 46 when running with 2.4GHz, all maxed out 16x/16x @ 1600x1200.
So, I'm not saying that your whole point in this thread is wrong, but as I posted before, "Anyone who claims they dont get a big drop in FPS with lesser cards at high settings and at high res are just kidding themselves." is.
Infact when I ran the game with my old trusty 9800pro while I had to send my old nVidia back, there was barely any drop in FPS at all, because I was playing with 32-35 FPS all the time and my CPU only awoke, when cruising over a city.
