As long as you've been hanging around AT, don't you have the routine down pat?
First, see how the system runs with what Abit included on the CD that came with the MB (or if you bought an OEM release, whatever the Abit site recommended for your board). After running that install, and any others you need, such as video adapter driver install, add-in sound card install, etc. then start some variety of burn-in tests and see how those go. AMD, or Intel, this part is going to be the same. You may not need the full nForce setup unless you have problems with what Abit offers.
