I went with the b450 tomahawk, have my CPU running an all core OC with ram clocked at 3800/14 and a 1tb gen 3 drive with read and write over 3000 so not sure how I'm not getting good performance from my 100 quid board?A couple of years is a long time, AM5 likely won't be out until 2022. I'd rather have a good featured and good performing board that will make the most of Zen3 in the meantime.
Later this year I will likely drop in a 3080 or big navi and maybe a 4700x/4900x so trust me I'm not going to be missing out on anything special for the next couple of years.
