does any one tried to mine something of this coins (MUSIC/ETC/EXP/UBQ) with R9 380? And how much he gets h/s?
There is no difference in hashrate if you mining with same crypto algorithm. All described above are Ethash, so the hashspeed will be same for all of them. I.e. if you mine Ether with 22Mh/s it will be 22Mh/s at EXP or ETC.
