I have an asus m4a785td-evo motherboard, amd phenomx4 945 denab cpu, 4 gigs 1333 mem, 800w pwer supply,thermaltake m9 black edition case.1 46" lcd 1080p tv and 1 24" lcd monitor. my question is, what would be the best video card to get that wouldn't bottleneck cpu. will be playing games like, badcompany2, crissis 2, and racing games.
5850 or 5870 would be solid choices. The GTX480 will also work for you, but its right at the $500 limit, and its not worth an extra $100 over the 5870. The GTX 470 is there as well, but its not worth the $50 over the 5850.
