well, i have been with AMD since i got back int PC gaming 7 years ago and dont regret it at all.
recently i got myself an XFX RX480 8gb card and took the crappy stock cooler off it and slapped a water cooling block on it. I must say that it, again, has never let me down. i play on ultra settings on all games 1080p and get on average 60 to 90 fps. it also runs great with my Oculus Rift CV1.
i play all the top games like COD BO3, Rise of the tomb raider, GoW4 and Battlefield 1 with no probs all on ultra settings. best buy in my rig at that price.
haven't gone into crossfire yet though as i seem to be hearing nothing but bad reviews on its compatibility issue.
