Look at the Claymore miners, and look in the ALT coin section. Your setup is just a waste of electric on bitcoin. Maybe ZCash or something like there. Also look at Cryptonight algo coins.
Mine for Ethereum if you have a AMD 470/570 or 480/580. If you have a higher end Nvidia then ZCash.... Extremely profitable at the moment. the 470s are producing over 4 dollars a day per card on Ethereum. Google how to mine on the net, way to long to even begin to explain it here. I am running 3 x 470s and one Nvidia on those coins. Very good returns...
