Hey guys, I'm frustrated beyond understanding right now because ATI can't put simple amp requirements on their box. I am thinking of buying an XFX 4850 1GB but this is the problem, I read on the AMD/ATI site that the card needs 75W to the PCI-E connector...I have absolutely NO idea what that means but what I'm asking is, can someone please tell me how may amps I need for this card per 12v? I'm not a computer expert, I just want to enjoy some shooters and this is preventing me from doing so, please, please help me anyone.
