I bought this RX580 back in November 2017 for what is currently a very good price. I tried installing it on my former system and it worked for a little bit (like an hour) then the buzzing noise, blue screen, and total PC shut downs started. After a couple of days of T/S I had to revert back to my old Nvidia GT750 Ti 2GB card and was able to keep on playing games as before.
I couldn't wait for 6-8 weeks to get another MB from MSI so I forked out $100's of dollars for my parts which you see above. It worked. Played for hours at highest settings. Meanwhile....I had decided to try out an SSD with my new build. I installed WIN10 but chose PRO instead of HOME so my activation would not work. I decided to go ahead and reinstall WIN10 HOME. Around 2 am the reinstall finished. All drivers updated. Back where I was before when it worked fine. Fired up XCOM 1 LW. Started mission, 10 minutes later....
I don't know what else to try except get rid of the card. The last thing I found to try was MSI Afterburner. I was told you can go in there and UNDERclock the card thus making it more stable. Others said RAISE some settings would fix it. I cannot seem to find a guide to UNDERCLOCK the RX580 and make it more stable (not crash). I have only tested it on XCOM 1 due to time limitations but that should not make a difference. I played XCOM with my Nvidia 2GB for over a year with never an issue, just lower graphics settings.
