It all depends on what you are planning for the future.
Every board would be sufficient.
if you want to upgrade soon or maybe add a 2nd gpu i would reccomend a board with a lot of pcie slots (1x,4x,8x,16x doesnt matter)
However if you just want to mine with one gpu, maybe a mini-itx board is a better coice. (this due to low power cpu's)
here are some sites which can help you:
