Answer 2

As far as I know, they will start, but they will work at the level of a pair of 7850. 7870 will be idle part of the time.
Theoretically, it will work less stable than a pair of cards of the same name - heterogeneous bundles are rarely used and, therefore, less tested.

Answer 3

I have exactly the same config as yours, only it costs R9 280x, so I want to pair it with 7850
