Sorry for the really late reply.
I'd suggest buying a different PSU anyways, because it will give you room to breathe later on when you want to add more stuff in. I'd say get a 750-800w PSU, or if you don't care about upgradeability, buy a 650w.
Also, I will be updating the thread with the new i processors and the 680 and 690 GPU's by nVidia.
