I don't know if anyone else has had any luck with the ASUS ROG EVO RX560 4GB, but I was able to achieve 510H/s at 44Watts on Cryptonight. I can get closer to 500H/s at 40Watts as well, this is after many hours and one serious custom VBIOS. I have tried to equate this to Ethash, but not sure, only assuming that would be close to 19Mh/s. I only mine Cryptonight.
