hey guys my system is a gtx 760 a i3 2120 3.3 ghz psu 500 watt motherboard H61M-S2PV 4 gb of ram. i think i have bottleneck with that i3 and i would like to decrease it with an overclock. does overclocking need more psu power? because i think i have my psu at its highest. and how much will it affect the cpu temperature? i currently have 31-36 deegres not on gaming. and last will it reduce the bottleneck? thanks for ur time
