No idea. Dont play those games, but according to benchmarks, the 7950 gets 57 FPS on Ultra 1920x1080 with 4x AA so you should be fine, especially with small overclocking.
A 7950 can match or surpass even a 680 when heavily overclocked.
A 7950 is your best choice. You can't really compare it to the 660ti as the 7950 (with the new driver updates) is better than a GTX 670 and is on par with a GTX 680 when overclocked.
