Additional Comments: I don't know much about pc building, I run an AMD II Athlon 630, 4GB Ram, 2 HDD ( 60GB for Windows 7 & 750GB for programs), Geforce 550ti Video card now & it just isn't enough. Noise factor isn't a concern for me. Looking to run games like Diablo III, and Skyrim on High or Ultra. Any help would be greatly appreciated.
If the PSU doesn't have enough wattage for that upgrade just get a new PSU too. With the 560 ti you would go well with an ~600-700w PSU.
Also, the i7s only benefit over the i5s is hyper-threading, granting ~30% more multi-threaded performance... Games aren't really multi-threaded and thus the i5-2500K would have indistinguishably close performance to the i7s.
