I recently put a 7790 in a machine with a 6670. The 13.4 and 13.5 drivers saw all the cards but if I went to any prior drivers the 7790 would not be seen. I'm using the 13.5 beta 2 drivers right now. I think the sdk in them is 2.8?
Also some other tests I just got done with. gpu0=hd7790, gpu1=hd6670
