I used the Z170A M5 for my two linux/470/570 rigs. Works flawlessly. But for VEGA was reading it's really finniky with boards. So I broke down and bought the slitghty more expensive (even more so on Amazon) Asrock H110 Pro+ board. I only need 4 of the 13 slots, but people reporting good results for Vega (even though the reviews people complain about it a lot).
