Is the 8600gt overlocked ddr3 512mb a decent video card?

well the 8600gts is the only one of the series that i would get for light gaming, and i would give it a 6/10

8600gt...i suppose would be 5.5 or something. I wouldnt buy these if you want to game alot. instead go ati

Go for an HD 3850. You won't regret it.

is the hd3850 up there with the 8800gt 512mb?

Don't expect to be running any AA with the new 3800 series cards, cause it kills performance. The 8800GT is the lowest a gamer should go with demanding games coming out these days.
