Probably would work well, but dang that thing is EXPEN$IVE for a mining-rig motherboard.
I'm generally paying ballpark $200 for motherboard AND CPU (bit under if I settle for a 4-core or 6-core, which would be more than enough for a pure mining rig - sadly the low-end AM3+ CPU supply seems to be drying up, as AMD ramps up more Ryzen in lower performance spots and probably has stopped making most of the FX line and lower-end parts).
I really wish someone would build a Ryzen motherboard with an 8x/8x/4x split instead of those 16x/4x splits (and if you're lucky a single PCI-E 2.0 4x 3'd slot) that didn't cost an arm and a leg.
