Switching from ATI Radeon 5570 to GeForce 7900 GT OC

[Countrybumpkin]

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!

First you need to uninstall the ATI drivers and software, then you can shut down the computer and replace the ATI Radeon 5570 with the GeForce 7900 GT. Turn on the computer once you have it back together and get into windows. From there go to NVIDIA Driver Downloads to download and install the right drivers for your OS. After that you should have to reboot the computer and then your done.
