Dual GPUs

[Jeff Grossman]

I have an HP P7-1254 which has an AMD A6-3620 APU in it which has a
6530D video GPU build into the CPU. It is supposed to support adding
a discrete video card and using both GPU for added performance. I
just purchased a 6670 video card to add to the machine. How can I
tell if the system is doing both GPU units? I can't find anything in
the AMD Vision Engine Control Center.

Thanks,
Jeff
