GTX1070 recommendations

So i've decided to build a 6 card GTX1070 rig after hearing how well they can perform nowadays with the new drivers, and claymore support.

Can anyone recommend some specific models which work well for mining? Which ones have superior cooling and OC capabilities?

Do they work well with dual mining ETH/SIA compared to AMD?

I've read that the "FE" version is best for mining, however it seems like they are almost impossible to find. Are there any other alternatives?

Thanks in advance
