My son played it for a while on an i5 2500k + RX 570, and it ran fine at 1080p. Not at anything like max settings, obviously, but it still looked pretty good and put out perfectly playable frame-rates (can't remember the exact settings and it did take a bit of tinkering but he ended with a up fairly solid 60+fps, I think, most settings medium). If anything you should have a slightly better experience with your hardware.
decided to take the chance and grabbed the ultimate edition for £33.99
hopefully i can get it running smoothly



Stupid slow 'fibre' broadband. FTTP in the area, hopefully coming this year. Can't come too soon!
