R5 430 does not support crossfire on the 7070 and its really slow. Closest thing you can game on is the DELL R7 250  2gig card. [URL] [URL]        
I suppose like a crossfire function?  Wondering if this was the purpose for having two of them?  Seems overkill to have 6 DP ports. (2 on the mainboard).  TIA
Just got my hands on a 7070 SFF with dual AMD Radeon R5 430 - Can I utilize 
both GPU's for gaming?
