I, for a long time, have not been happy to run at 60hz (even back on the old CRTs I used to drop res for higher hz, preferably 100hz or a min 85hz because even 75 seemed jarring at the time). Having said that I cannot tell the difference between 120 and 144 and have found those extra hz can "wash out" the colours a little more than desirable (something I hear others mention too, but not sure is that just a tn panel trait?), so have resorted to running at 120.
I do kind of envy those that are happy to run at 60hz as I can see how it makes things easier to run with more "eye candy" settings while avoiding the frustrations of games with capped fps (or the undesirable effects if unlocked).
Thankfully there are setting that can be dropped, or lowered, in many modern games that I really dont care for or think add much IMO(mainly screen effects, high shadow settings and lighting etc), which help to achieve the desired fps. You are likey to have to do this with a few games with a 1060 too.
Now that you have experienced higher hz, I think you will find it hard to go back. In any case, I hope you enjoy your experience.
