have you disabled the integrated graphics?
Nope. I set it to Force and 1GB UMA Buffer Size.
Seeing AMD's reports, the recomended graphics card fro the A8 is the 6570, that said the 6670 should be showing on the catalyst menu.
AMD Said: Make sure you have downloaded the latest AMD graphics drivers. After driver installation, the option to enable AMD Radeon™ Dual Graphics should become available in the AMD VISION Engine Control Center.
Once installed, go into the “Performance” section of the AMD VISION Engine Control Center and check the box that says 'Enable Crossfire™' - this will allow the AMD A-Series APU graphics to work in tandem with the select AMD Radeon™ HD 6000 Series GPU installed for increased graphics performance.
-It should be there but if it isn't the GPU must not be compatible with the CPU
