Hi just needed some specific help. I used to do alot of PC upgrading but now money is tighter and i have less time. Iv tried doing my own research but i would like some proper clarification from "pros" so to speak.

Im wanting to upgrade my current system :

-AMD Phenom II X4 970 Black Edition 125 Watt Socket AM3 3.5GHz 6MB

-GIGABYTE GA-870 A UD3 mobo

-8BG of 1333mhz DDr3 ram

AMD HD7850 2gb OC GPU

-Casecom Silver 500W ATX Power Supply - 20+4pin ATX12V 4x Molex

Curently i can run all games on medium settings with 40-60fps. However i feel massivly bottle necked with my mobo/cpu, as my mobo is runing of a 4 pin adapter in the AT_12v_2x4 pin. WIll this lack of voltage be effecting my CPUs performance?

If so What would be best upgrades to get this to run at better fps

THanks guys
