I was looking to buy a motherboard for a system with a xeon 1231v3 and a r9 290 (later I'll add another one in crossfire). I've narrowed it out to these 4(pretty similar prices with the GB being slightly cheaper). I know I won't be able to clock the xeon - I am getting a z97 and not a h97 just for the x8 crossfire. From what I've read on newegg, each of these has had some issues so I am not too sure about the choice, and in a certain review I read that the GB has a higher power consumption due to some firmware update.
