I think you got your GPU and PSU mixed up. :P
Anyway, yes you'll be able to overclock with those specs. I'd suggest the Cooler Master Hyper 212 + if you're going for a budget cooler and the Scythe mugen 2 rev. B, Thermalright TRUE or a the Noctua NH-D14 if you've got the money to spend.
Good luck with your overclocking.
