You may think I'm nuts, but processor upgrade to new .45 Quad makes a major differenc
I upgraded the processor on my Asus P5E motherboard from the E6750 to the new Q9450 (both 2.66 GHZ, but two extra cores to work with). My old Crysis benchmark for fps at 1680 x 1050 was 22 fps on average. With the Quad core...ran the same benchmark and averaged over 36 fps. There is obviously a tweak in Crysis for Quad core. The only other change is that I am running Nvidia Forceware 175.16.
