I am about to get an xfx gts 250 1 gb. My cpu will surely bottleneck(core 2 duo 1.8 Ghz)(e4300). By how can I overclock it with a stock cooler on an intel d945gccr motherboard?
A modern 550W PSU should have at least 36A (combined) on 12V. Check that you're not getting last gen. ones which are still floating around on market.I will be getting a 550 watt powersupply.
