It's not the same as a 980X as it has a different microcode and doesn't have an unlocked multiplier.
It's still a Gulftown and should still work fine in most desktop boards, even if the board doesn't have official support for it. Might not display the correct name on boot, and might need to be manually configured, but there is no reason it should not work.
The only functional differences are that the Xeons support ECC and the second QPI bus is enabled on the X line of chips. Unbuffered memory is still supported and a the second QPI doesn't get in the way of anything.
