Yes, but I'd recommend picking up a airport card from a 2011 iMac to fit in later, I get consistently better signal strength and speed with using the iMac 3 antenna card vs the mac pros 2 antenna card.
They're only 11n, but 3 antenna's mean a theoretical peak of 450Mb/sec versus teh 300Mb/sec of the 2 antennas, assuming your base station also supports it.
It also supports the 5Ghz spectrum by the look of it, which is a bonus.
That said, I can't see anywhere obvious to order it from, or a part number for reference.
I've got one of the cards as per your link, they work fine, but they're "only" dual antenna, and only 2.4Ghz. A PCIe 802.11ac card might be a better option - if you can find one that's compatible.
