Its really dependent on your systems cooling but all cards are different. Your 1060 should get you through gaming the next 2 years in its current state but i would start saving your pennies. More and more games are going to be implementing ray tracing (RTX Cards) down the road. People say RTX will be a slow effect on the industry but people also said we would have 36 core processors by now, were all wrong at some point. But the brass tax is tech in the computer world is on the up and get ready alot of games will be changing how we play games and builds systems sooner then you think.
 
But to really answer your question your results will be modest to say the least if you boost it at all. The issues lay with the memory bandwidth(192-bit) not so much the speed of the card, they do clock quite well same with the memory but you lack cuda cores and lack 256-bit mem bandwidth.

Hope this gives you a tid bit of insight into what to expect.

Great Test , those are the results i was kinda expecting. +1 for sure :) answered your own question too for the most part :)
