Just for a change it's not ATI's fault this time! nVidia have been struggling to release a decent unified driver for this board ever since it's release. There is a new driver release that is supposed to show it's face any time now, but with the release of new drivers, nVidia usually follows up with a withdrawel of the same drivers within a couple of weeks, then they put the old ones back up at their site!
I am currently running
Omega driver for my 9700Pro, I have only had it installed a couple of days, so I can't guarentee stability yet! Apparently it works with all radeon cards and includes an o\c utility. Just click the "ATI Radeon" link at the side of the page.
note: you must un-install ATI control panel (Add\Remove programs) before you install this (Catalyst 3.6) driver.
