The thing is, i'm only planning on playing 1080p and most if not all benchmarks show only a 7-9% difference between the 3gb version and the 6gb version of the gtx 1060, and considering that the difference in price is significant where i live ($100 more or less) i'm having my doubts about it...
Well, the 1060 6gb is better overall and will age better. the gap between the 480 4gb and the 1060 6gb is closer than the 1060 3gb and 6gb, especially in DX12, which more and more games are moving to. I suggest checking the price of the 480 4gb and see if its the same as the 1060 3gb or a half way point between the 3gb and 6gb.
Plus, the gap between cards heavily depends on what programs you are looking at.
