The biggest question that comes to my mind here is what is the value of the ASRock Extreme4 z97 3 way CFX/SLI? I see that the speeds for each slot reduce to 8/4/4 for 3 cards opposed to 8/8 when you only have 2. Assuming I could fit all 3 cards in the case comfortably, would the reduced PCIe speeds allow for worthwhile 3-way performance? If the third slot on the ASRock motherboard provides minimal extra value, then the Asus might be the way to go.
