You can set streaming to either run off your cpu or gpu. Obv running it off either means that which one you choose has to be able to process the data going through it while still allowing you to pew pew.
Eg: laptop with gtx1070 and i7 but running streaming off the onboard intel gpu so it doesn't effect the performance of the game.
Best cpu will obv have multiple cores, so say a 2700x or a 9700k.
