Yes, when installing a WHQL, sure. However, this thread is about the beta? For a beta, you must get rid of left-over stuff, like overdrive profiles and such, maybe some registry keys. I always remove driver as you say, but before reboot, I manaully delete AMD folder on C:\, and then remove AMD/ATI listings in the registry under the "SOFTWARE" sections of each main heading. Then I reboot. Not much more than a normal install, really, but I found it fixes issues with Overdrive when swapping cards, so now I do that each and every time I change drivers. ATIMAN and all that other stuff aren't needed, IMHO, unless perhaps you run full AMD rigs, which I do not.
