I just upgraded from a 8800gt 512 to an evga gtx 660 sc. In the games ive been playing i have not seen too much increase in my fps between the cards. im running a q6600 at 2.4ghz with 4gb ram on windows 7 32bit, the 660 is also in a pci-e 1.1 16x slot. do you think my cpu is holding/bottle necking my new gpu? ive tried overclocking but my nvidia chipset hates the core 2 quads with my zalman cooler
i have the same cpu and i was happy with it, i buy a new palit 650 gtx ti i feel the same olso in games and i deside to go for amd fx 8core series and a new mobo
i dont know if the 3750k worth it for the money some veterans here mby give u better guide in the specific platform
OCing your CPUs would help, those chips can do 3.0 easy 3.6 with proper H20 cooling... they're stout chips just dated by their architecture... i went from a C2D e6850 to the 2500k and it was light and day the speed difference.
