You're good to go, assuming you're running a 64-bit OS.
i had that combination and opted for 660 instead of 650ti so that i am not bottlenecked by gpu again
i had 30-40fps in bf3 mp and 50+ in skyrim tough had 60% gpu usage in bf3 and 80% in skyrim (high textures).
Hah, you picked what are possibly the worst two high-profile examples. Both MP BF3 and Skyrim are CPU-intensive, so there will be a slight CPU bottleneck there. You'll see higher GPU usage in pretty much every other game, however
