As someone who bought a RX580 for playing with Deep learning with ROCm (It was supported at the time). After posting to one or two bug threads, I had the same experience as the gp -- our issues were ignored. The issues have recently closed as the RX580 is no longer supported.
As for long term success, good luck, but once bitten twice shy.
