Getting new GPU

So I am planning to get a new GPU unfortunately my budget is rather small so I have been thinking about 1060 6GB or RX 480 8GB I am not sure which one would be a better choice. Mostly I am running algorithms like salted MD5s and SHAs with dictionary attacks. 

If I went for a 1060 I would most likely choose a nonreference one (thinking about Palit GeForce GTX 1060 Dual 6GB) or maybe a reference one would make a noticeable difference. I need to, because 1060 FE is like 50$ more expensive.

Thanks everyone for a reply.
