wanna upgrade my pc one last time before i rebuild its been pretty good to me lasted me about 3 years. was thinkin 6850, I don't wanna get anything to powerful my e5200 is a little slow even at 3.06. I usually game at 1080p on my monitor but lately its been 720p on my tv. is there a better deal than the 6850 in the 125ish price range?
