I bet if you tried every flavor and hack of the Catalyst 3.7 drivers out there, none of them would make more than 2-3% difference in anything. I would recommend ATI's reference driver or the Omega Drivers.
The official Catalyst 3.7s work for me, I have the 128mb version and I updated from the 3.6s that came bundled with it. Didnt notice a difference in usual desktop use but I did notice a rise in fps in games.
Ep, glad to see you come back and tidy up...did want to ask a one day favor, I want to enhance my resume , was hoping you could make me administrator for a day, if so, take me right off since I won't be here to do anything, and don't know the slightest about the board, but it would be nice putting "served administrator osnn", if can do, THANKS
