I do not get here all that often....
I am running a pair of 290x's and they work very well.
Too bad your 280's are gone, there was a setup problem with them. The 970 is a good card, but no where near what the 280's are.
I would start in the BIOS if you have more trouble, check your PCIe lane settings for each slot.
