You're in luck, I've got PowerColor RX560-4GB Mining OEM (Hynix) cards. The little darlings were a beast to tame but I got them very stable at 400 H/s (Claymore v11.1). They're aslo relatively good on power but I don't have any real numbers except GPU-Z.
The red devil should be the same card but with a different plastic shell.
edit:
How very odd, both the ROM on my hard-drive and the post I made about it here to share the ROM are gone. Only an older less stable version remains... except for in the cards EEPROM and they're currently mining.
edit_2:
You'll have to wait 'till later, I can't remember what frequency I stabilized them at...
