Tell me how to use this on my PCIe-less Mac Pro. I really miss the expandability of my old 2006 Mac Pro.
Seeing that there is Thunderbolt connected Intensity product, I suspect that pretty soon there may be an Intensity Pro as well. May even use Thunderbolt 3. [Pure speculation, I have absolutely no inside information]
Of course, if you absolutely want this now, there are PCI-E chassis that connect to your MP using Thunderbolt 2 - though they most of them cost way more than the card itself.
