Hi guys I recently purchased a new PC from HP that came with an ATI Radeon 5570 installed. I don't like this card, and I have an older PC with a GeForce 7900 GT OC in it. Would it be possible to do a clean swap-out with these two cards? Do i need to download the GeForce drivers onto the PC first? I'm a newb and have never switched video cards out before so I don't really know where to begin. Any help would be appreciated. thanks!
