I am building my next rig, based on 1060 cards. I am having trouble in deciding if I should spend some more on the 6GB version.
It is my understanding that 3GB is mostly problematic when mining Ethereum which I don't, I prefer to mine Equihash coins .
So is there a reason to pay extra for the 6GB card?
Its not just a memory difference. The core count is a bit less on the 3Gb card (1152 vs 6gb 1280).
So they will always hash slightly less. If you dont care about Eth, then get the 3GB card. The best deals will be on those for sure.
