thanks for the great info! i wanna build a pc and was wondering if i could get a mild overclock on a fx-8320,(to 8350's speeds) and have two msi r9 290 overclocked to around your first overclock 1100/1350 on air cooling of the msi twin frozer IV's and not exceed 95 C in a corsair 230t case with all fans blowing and the GPU fan going at 100% and still be good on the power side of things. the build would have a corsair ax860 watt psu ,6 case fans,(3 120mm and 3 140mm), 1 ssd, 1 hdd, 1 dvd reader, a MSI 970 gaming mobo, G. skill sniper low voltage Ram ,(2x4), a XIGMATEK dark knight 2,(with two fans) , plus a wifi card. Sorry for such a long post just wanted to put all the details in it.
