Installing Nvidia drivers on Fedora 12?

I currently have two video cards on my computer. An ATI RAEDON that came packed into my motherboard, and an Nvidia GeForce 9800 GT that I purchased as an upgrade. The live disc would not boot with the Nvidia, so I took it out and am currently installing using the ATI card to use it. When I plug my Nvidia in again upon reboot, will I be able to install the driver flawlessly? I have had some problems in the past with Ubuntu based systems, and I would like to know if Fedora is the same way.
