Just got mine in today and 3.2-3.3 gps on grin and ranging fro 18-22mhs on Raven.  Gminer wouldn't start on SMOS to try Beam and need to make a config for Aion, Eth, and some others.  Need updated drivers in SMOS.  The card is recognized as a Gigabyte Graphics device instead of the model  of the card.  Going to try out windows when I have more time.  Just finished 12hr shift and work and have two more the next two days
