I would like to see XMR come into the picture as a profitable coin for the Nvidia cards.  Just having ZEC really makes this a hard sell for me to buy some 1070's.  I have a rig I need to retrofit with some updated cards and I am considering the 1070's for this rig.  

I would like to add some diversity to my rigs to give me options if things start to go bad for the AMD cards the Nvidia cards may be able to help stablize the cash flow, and vice versa.  Having different cards with different strengths could be a real bonus.  So I was hoping there was some activity to improve the hashing on some other coins to help make the sale that I should add the 1070's into the mix.  It is a hard sale when the cost is so high for these cards.  So I am just looking for some more bright spots for the 1070 to help make the case for spending the extra money.
