BSODs in certain games are a known issue, I'm sure its being looked into. AMD overdrive works fine for me (v4.0.5 if I'm not mistaken), older versions did not work. Had the "ES" bug in CPUZ as well, nothing to worry about.

I also have Turbo Core disabled in bios, but I still need to enable and disable it one time after boot in windows using AMD Overdriver, or else cores will drop to lower freq. when under load. I still think this is what you are having issues with. So make sure all cores really are running at the max speed under load, or else scores will suffer a lot.
