Hardware Unboxed has reported the MSi MPG X570 Gaming Carbon Pro WiFi as probably the worst AM4 motherboard for the AMD 3900X/3950X CPU. The crappy VRM design makes it hit 95+ degrees under load while other boards can be as much as 40 degrees cooler. This board is only acceptable with a 65-watt Ryzen CPU.. But if you wish to upgrade down the road to a faster CPU, then avoid any MSi board below the MSi Ace at all costs.
I have the Gaming Carbon Pro WiFi and can attest to the fact that this board's VRMs do hit 95 degrees when encoding videos. I thought it would be safe buying a midtier MSi board but I was sadly mistaken...
