What are the hashrates for GTX 980s?

I recently bought an Alienware area-51 r2 which had 3 x GTX 980s in there and being the shekel goblin I am, I decided to mine raven coin on it (I would have mined ETH but these are 4GB cards so I cant) Im getting 1.5 MH/S for GPU 0, and 1.6 MH/S for both GPU 1 and GPU 2. It seems to me that I have extremely low hashrates? wtf is going on?
