Game is very single core so intel definitely the way to go faster single core clock speeds  . 16 GB bare minimum ram. When streaming to be fair if you have a good GPU can stream pretty much anything since most streamers lock fps to 60 run at 1080p most of the time but stream 720p because a lot of people have slow internet connections . I have a 2070 super with a I5 8600k can stream anything was doing control on max settings etc
