So got some funds for my 3rd Rig it's going to be 1060's but should i go for 3gb or 6gb?

6gb. 3gb may become obsolete for mining ethereum in the not too distant future.

6GB will be the new standard of mining OP

Pretty sure this, there is some very difficult work around so you can boost your 3GB that it can keep mining and possibly hit the ROI but this would require you to physically change things in your GPU. This will require expert knowledge of hardware.

I would suggest to just go for 6GB. Right now the best options for cost/mhs are:
Evga 1060 6GB dual fan
Msi 1060 6GB single fan
