I bought an XFX 7850 Core Edition 1gb from Newegg and I just installed it today. The problem with this card is that it coil whines on startup until I log in to my profile. Do I need to RMA this card? I thought that an 450W XFX Power supply would do the trick but nothing is wrong with it. I even took out the card just to make sure and the card seems to be the problem.
