I would say the 1060 would be a lot better in newer titles, the 780 really does not hold up very well in newer titles from regression testing I have seen. 780s in sli would likely perform better in games with proper sli support, but proper sli support in games seems to be more and more rare as the years go by and it looks like that trend will only continue. Also 780s in sli will have more than double the power draw of a single 1060.
