I will soon own my first Nvidia card, an XFX 6800 Ultra (AGP). I have no idea what drivers work well for benchmarking and what works well for gaming. What are the best drivers you guys have used?
I tend to have no trouble goin with latest betas (www.nforcershq.com is a good place to look, like guru3d). If theres a specific issue just roll back to the ones before or latest release. New drivers can make some difference but its only large near the start of a cards release, as of now performance for your card should be pretty close across the last 2-3 beta released.
If you are really wondering, best thing is to bench a few and pick one!
