First thanks everyone I've bugged and who's helped me out - you guys are great and there are so many awesome people here!
After TONS of reading and then more reading and searching and a few questions I finally built 3 dual GPU rigs to test out for myself.
For my test run I only bought:
2 RX 470's
2 1070's
2 1080 Ti's
Here they are
Currently just running NiceHash with Claymore Dual Miner but if anyone can suggest something better I'm all ears
The nVidia's I have on zpool using nemos 1.7.3
Always looking for better way to set up -
In the garage I also have 8 more RX 470's but I just bought 10 more 1080Ti's to replace the RX 470's since they are not earning much on NiceHash at all.
I don't have anything flashed, the nVidias are just tuned a tiny bit with Afterburner.
Thanks again for all the awesome info - my journey couldn't have even began without all you lovely people!
