Just install the first one. The beta driver is for experimental purposes and you probably don't want to be bothered. The Profiles are only if you 2 or more graphics cards installed.
Thanks for the quick reply! okay so I've download the first link and installed it, restarted. Is everything all set? But if I go to my device manager and under the driver tab, the driver date is still listed as 5/17/2010.... Is this normal?
Also for the profile file, after reading the notes underneath, it says its good for single or multi GPU, I think I have some mouse flickering problem when I play Diablo 3, so do you think I should get it still?
