Also you psu is a bit overkill, for a 6850 or 6870 a quality 500w psu is more than enough.
Wow thank you so much, I was originally going to get a 650w but my friend said for sure I'd need a 750w at least, now I can get a better PSU with a lower wattage.
Anyways, I've already purchased my GPU, HDD, and Case. I think I'll stick with the Hyper 212 then. I'll look at more benchmarks before I pick the Plus or EVO though. I plan on OCing in the future and unlocking the 2 extra cores.
