I've tried the 56.56 beta which i got off of msfn. I wouldn't keep my hopes up, the auto overclocking doesn't come with the driver, you still need to download coolbit. And all I saw in all the games i play were performance decrease(UT2k4 demo, Halo, SOFII,(DX8, DX9, Opengl)). Doesn't matter to me now since i'm going back to ATI.
NEED NEW SYSTEM!
