any mic, I dont say especific, my combo is akg k 712 + schiit stack + blue yeti, but there are others similar, just dont spend 150$ on a crappy headset with a 4k$ build, he can spend from 100 on a blue yeti to 35 on an amazon basics (snowball like), I have both and any cardioid around 40-50$ is good enough for streaming. But with that budget oh my, I would rather buy a 2080 + 9700k and have a monitor + good sound than a 2080ti + watercooling, but the best part is if op gives up about watercooling he can have both , 2080ti and all that perks, watercooling sux, my nhd15 can trade punches with any of those.
