And it will certainly perform better than a ps4 pro in most games. We don't really know Scorpio so idk about that. What I do recommend however is to spend $150 more on a 1070 instead or wait a couple of months until AMD's Ryzen 5 CPUs come out which may lower the cpu cost more. Also add like $20 more for Windows 10 from Kinguin.
