Yes Calnin you're right but 90% of them are better than the stock ones...
jr74752 if you didn't buy that motherboard and PSU yet I would suggest you to buy one of these 3 motherboards if you plan to overclock CPU
ASRock 990FXExtreme9, Asus M5A99FX Pro R2.0, Gigabyte 990FXA-UD3 (buy the cheapest one because they are all good and very close performance)
and I agree with Calnin with the PSU, i don't like corsairs CX series either, they are poorly made... Would go with xfx/seasonic/evga/rosewill < any of them 4 over corsairs CX
