The 5800x3d will still be faster a lot of time than say a 3900x or a 10900k, not really slow (would need some *, like for the price or something)
Hard to imagine someone looking for a 5800x3d is not mostly into game and how relevant it is too.
Depends what you do, the similarly priced 5900x in a Unreal project code compile could take minutes less, baking the lighting half the time, lot of workload are counted in tens of minutes-hours:I'm not your "bro" and it's literally a couple seconds at best or milliseconds difference in performance you are talking about.
