Recently I bought a MSI FM2-A85XA-G43 motherboard with a AMD A10-6800K, all was well, installed the OS, then I wanted to enable AMD Dual graphics, which just doesn't work right.
I went to the BIOS, enabled Dual Graphics, and set my Radeon HD 6670 as primary GPU. When checking the Performance tab in CCC, there's no option available to enable CrossfireX, and the iGPU of the APU has been disabled, unless I would connect my secondary monitor to the motherboard resulting in one of the two monitors getting no signal when the system boots until Windows has been booted.
What should I do? This is VERY annoying.

Thanks in advance.
Have you tried setting your default GPU to the iGPU?
I could be wrong, and please feel free to correct me if I am because I have more experience with Nvidia GPUs than AMD, but don't both GPUs need to be of the same or similar series in order to have Dual Graphics/CFX? I don't think a Radeon 6670 is meant to be compatible with a Radeon 8670D because they're from two separate series (6xxx and 8xxx, respectively).
pretty sure you need to have two identical cards to enable crossfire. as lordgeorge said, you can't have two cards from two different series to work together
The 6670 [I]should[/I] work fine with hybrid crossfire:

This is what I was thinking too. I read it is possible to do this. I'm gonna check out that tutorial tomorrow as I have to go to sleep soon.

benchmark of it
I already tried a lot of things at this point, I reformatted my computer without the GPU installed, no dice.
