If you wants to stay at min 60+fps in games like 64 maps bf3 1. Crysis 2, and Crysis Warhead
2. Metro 2033
3. ARMA II.
6.skyrim+8xSS + mods
7. Alien VS Predator forget it not going to happen with either of those cards but as mentioned above. The 7950 is the more powerful card, and both of them will run games beautifully at 1920 x 1080.
