I just switched to the Omega version of 6.3, and I like them. Good stability, IQ in games seems a bit better, (may be my imagination, but...) My X850XT/PE AGP crd h as overclocked a bit farther with them, than under the official drivers too. Now THAT may just be co-incidence, but I never got past 590/600 with the ATI drivers, and now I'm at 600/610 with ZERO artifacting.
