X7 390 - what os / miner

Hi all I've got x7 390 8gb and I want to get them mining zec, what os/miner is giving best performance currently?

I haven't got those particular cards, but Windows 10 AMD 15.12 drivers and Claymore 12.4 miner works superbly.

only thing I can really add is if you are doing windows 10, make sure its the pro version! Pro is a lot easier to make sure it doesn't download pesky driver updates!
