What components do I need to stream?

I wanted to start streaming, but I need a better mainboard and a new CPU. Does someone have a "bundle", i.e. A mainboard and a processor to recommend?

Would Play & Stream Games Like:

Minecraft, Csgo, DayZ, fortnite

Ideally a ryzen 9 3900x with a b550 chipset, which does not come into the house otherwise
