The 1060 would be a huge improvement over the 760. I personally have an old 770 in another machine, and am considering upgrading it to a 1060, because the 1060 gets nearly double the FPS in a lot games over my 770. So compared to your 760, the performance gain is even greater. Once upon a time, I found some benchmarks comparing both of them directly, but that was difficult to find because of the generation gap, and I can't find it again. But indeed, the performance increase will be very, very noticeable.
