For me at least these releases are not going in the right direction.

All 3DMark Extreme tests were run within the same 24 hours and on the same and hardware with latest 12.7.CAP3 profiles. Catalyst manager was used to uninstall drivers and Crossfire setting was re-enabled (toggled) prior to each test.
