hmmmm, maybe my criteria was to make sure i had dual monitor cap. for future.
But, not sure, really thought it had to be 9 series. As well many reviews i read 
about it had 9's and I doubt they had dual monitor criteria.
Maybe Clifford has thoughts on if he believed he had to do 9 series as well.

Well as far as I can tell from nvidia's specs, any Geforce 600 series and
higher can do 4k@60Hz with displayport 1.2 if the card has a displayport
connector.
