Listen to the man. I just finished about a month of running the 93.71 drivers, and they are pretty unstable on my 6800, in more games than just AH. There's no good reason (performance-wise) to use anything beyond the 66.93 drivers. Everything after that focuses on the 7xxx series cards. Still, any of the 8x.xx series drivers should be stable, if you just HAVE to have newer drivers.
