The CPU is fine, and I have a 1440p monitor so its not a huge bottleneck, I don't need more than 60FPS.
Vega 56 takes 210W, and the BIOS won't let you go over 300W no matter what. with undervolt I think it is going to take aroud 190W, which is good for a 500W PSU, but it can jump to 300W for a few seconds at any time, and this is the scary part.
