Perhaps availability of Zen3 desktop APUs will alleviate that particular market.. if they aren't OEM resticted. I'd certainly build with one. I have a Lone Industries L5 case waiting to house something along those lines!
Depends on use case though.... I'm going to be running either an Rzn5 3600 or a Rzn7 3700X in my main "office" PC but won't be gaming on it at all so I want a relatively beefy CPU for things like Lightroom, but my only concern for GFX is that it do 1440p @ 120hz + .
I don't think an APU is going to be sufficient for what I want cpu performance wise.
