I've finally decided to upgrade from this 5600, I'm getting the limited edition evga, best card for 300 bucks. The only thing I'm worried about is my psu. I have 3 case fans, a 12v water pump, dual 120mm fans, 1 sata driver, 1 pata drive, 1 52x cdrom drive, an audigy 2, and a p4 3ghz. Should I upgrade my truepower 430?
