Since that commit Rx 480 supposed to be recognized, but I am using closed source drivers, because the audio patches arent in upstream yet. I found a real problem from SC2 appdatabase and I could confirm it myself. When you start SC2 and go to options it limits your GPU graphics options. With the attached patch here the options are not limited anymore.
