Whats your whole system specs?
I'm running a 8600GT on a 300W HP PSU, which is essentially an 9500GT with a older manufacturing process that uses more power.
LOL it was actually cheaper! because the 9400GT had tax but the 9500GT didn't > thanks timop, shovenose and everyone who helped out! i'll tell you guys how it turns out in a couple days! [:whew, didnt know why you want to get less for the same money there. LOL
