I slapped this one together last night and then took it to work with me today. I set it up in the build station and installed Win7, drivers, and most of the updates through the day as I had a little time. I was able to get AMD's dual graphics working (I think)... there is very little in the way of concrete instructions out there. AMD VISION Engine Control Center says it is enabled, but I have to hook the monitor up to the APU output instead of the graphics card so I am not overly sure; hooking it up to the graphics card gives me nothing.
Anyway, I am finishing up the updates right now. I will run the Unigine Heaven benchmark once I am done to see how it does.
EDIT: OK, I have run the benchmark on both this system and my own.
Here's my results (Phenom II 965 x4, 8GB RAM, GTX560 Ti):
The result for this machine is (non-graphic):
Min FPS: 13.2
Max FPS: 52.2
CPU: AMD A8-3850 APU
GPU AMD Radeon HD 6570 CrossFireX
Both are using the same settings.
