ps. gtx 660 i can buy is not "golden sample" but now i see there is very little difference.
I plan to manualy OC graphic card, and i heard 7850 can oc extremly well, but i know very little about gtx 660, especially about Gainward
. I will buy XFX 80+ 450W psu btw.
Please guys, give me some advices, and ignore the price differences because 7850's are 253$ (in my country) and GTX 660 is 255$.
