Very nice Motherboard Tony, I am not sure I understand your question but if your asking if your board will support using a SSD the answer is yes. I would look for SSD that is USB 3.0 to take full advantage of your hardware.
As long as it's a standard x4 card, you shouldn't have a problem using an x8 or x16 slot.
Generally, the lower numbered card can be used in the higher numbered slot.
