If you're on a somewhat comfortable budget, you can get away with something along the lines of a 1660 where you shouldn't really experience much lag for 1080p, 60 FPS. If you're on a tight budget something along the lines of a 1050 ti. But again, I'm not a professional. I recommend joining KristopherYee's Discord Server. Everybody is friendly and willing to help you since they've been into PC's for a *long* time.
