Well my question is which GPU is better the GTX650-DC-1GD5 or the HD 7750 Radeon, I currently have the 7750hd, given the case that the 650 is better will it run on my 325w hp custom PSU?
 
I appreciate your replies, thanks a lot....but isn't there a difference between the normal 650gtx power requirements and the Asus "low profile" version? its 63w requirement and the HD 77750 @ 55W
