Yes, I already own it. My dad bought this PC for me. The games run smooth with high graphics, I wanted to know if it's good for gaming because I'm not that good with PC components..
Short answer: If it runs smooth with good graphics, it's suitable for gaming
Question always is how long it will keep running smooth on high graphics, but as long as you don't mind turning graphics down I think the 1060 (even 3gb) will do fine for a while.
Quite some time ago I read an article about 3gb vs 6gb, don't know if I still can find it, but it turned out the 3gb version is not that
much worse than the 6gb.
