I run the 970A with 5x 280x's from sapphire and 2x 750w Gold PSU's. Just get the cheapest CPU that has the same socket type as your MB. You definitely don't need 16gb of ram, I use 4gb. Everything looks good though. You'll need 3 16x-1x PCIe Risers though to keep them cool, you can use the 1x side in the 16x slots and it won't lower any performance
