Going from onboard video to AGP

[fwtong]

I've never gone from onboard video to an AGP card because I've never used onboard video. But, I'm droppoing my old 9800Pro into my Mom's computer, who was using onboard video from her NForce motherboard. Do I have to uninstall the Nvidia NForce Drivers and then run run Driver Cleaner? If I run Driver Cleaner, am I going to have to reinstall the Nvidia NForce Drivers?

You need the nForce drivers for the chipset, so don't uninstall them. I would just install the card and the ATI drivers. You should be fine with that. If there are ForceWare (video) drivers installed, you might want to run driver cleaner on those. Even that probably wouldn't even be absolutely necessary. I've heard the stories about going from NV to ATI and from ATI to NV, but I've never had any problems myself.
