I just upgraded my video card from a nvidia 9600gt to a gts 450. Right away I noticed that I was getting really poor performance in games and programs. I did some research and figure it's probably because my psu is rather poor, a 450w Radimax and is not getting enough power to the card. I just got back from my computer shop and they recommended I get their Coolmaster Extreme 500w psu to replace the radimax. Should the 500w Coolmaster be enough to sufficiently power the gts 450? and is it a fairly good quality psu? thanks
Intel q6600 quad 2.4gz

it will run, because the GTS 450 is a power efficient card rather then anything the CM 500w can provide. there are better PSU for the money. Do you live in the USA and have a budget?
