I was just about to try the beta 12.7, but I'm currently using the 9.1 which came with it.
Yeah, first you need to update those drivers. The 9-series drivers have to be three years old already. As well, the latest Catalyst beta drivers are 13.2 iirc.
So yeah, download a new version of the Catalyst suite, uninstall your current drivers, and install the newer revision.
