I'm not disagreeing, but Nvidia has a very effective memory compressing algorithm with the 10 series... So that may be mitigated even more so. That said, 4gb of ram sometimes does come to the rescue for certain games. Ultra settings are usually not well optimised and some times can not be noticeable when you are speeding through a game. But to answer the posters question, neither is really a better option. They both are very similar, and while the 1060 is arguably faster, especially after factoring in the CPU... It may be bottlenecked by it's ram.
