Buy this gpu RX460 4GB Gigabyte, unmodified. When mining Musicoin with Etheminer the temperature of the GPU shoots to the 78°C, it takes to guarantee, I returned to the days telling me that in stresses it reached 62°C as maximum (also that card I rebooted the pc after a few hours ) I'm testing it now if I restart the pc again. I have a RX470 4GB that has a year of use, it works normal in 69 ° C without that I restart the pc.
