I'm looking at these two motherboards
ASRock Z170 Extreme4
and
ASRock Z170 Gaming K6
They are both within my price range and was looking for something that could run in SLI even if it is just 8x and 8x but still run an M.2 SSD. I saw these boards have the Ultra M.2 and was wondering if I used this ability and had a GPU in one slot if it would take up lanes and knock it down to 8x and use 4x on the ultra m.2 or if the ultra m.2 used pcie lanes that were already allocated by the motherboard and would leave the gpu unaffected.
