No. I'm not sure what that would accomplish. Please share more of that thought.

Just to see if this is some sort of mainboard slot problem. Maybe Slot 1 likes AMD more then Slot 2 because of pcie slot power usage?

I don't know what that may accomplish. Please share what you may know about why that may affect performance.

I know it is just a speculative idea and maybe does not change things at all. If we assume the mainboard has a power issue when both GPUs are folding. And each GPU pulls power from pcie slot up to 75 watts. Maybe the gtx 1070 pulls more or less power then the R9 290X and just swapping the GPUs could lead to a different power usage in the 2 slots. Which may help the mainboard to run both.

I also see the mainboard has a 8 pin power plug. Can it make a difference which power supply cable goes to mainboard and which to GPUs?
