Hello,

I want to invest 20000 € in a few mining rigs. The big problem is that the most amd GPUs are not available, so i have to take nvidia GPUs. I would like to get the max. possible Mh/s for Ethereum mining and to build some 6*GPU-Rigs.

I can get following GPUs:
- ASUS Dual GeForce GTX 1060 OC, 6GB - about 300€
- ASUS ROG Strix GeForce GTX 1060 OC, 6GB - about 330€
- ASUS ROG Strix GeForce GTX 1070 OC, 8GB - about 500€
- EVGA GeForce GTX 1070 FTW Gaming ACX 3.0, 8GB - about 480€
- ASUS ROG Strix GeForce GTX 1080 Advanced, 8GB - about 600€
- ASUS Turbo GeForce GTX 1080, TURBO-GTX1080-8G, 8GB - about 530€
- Gigabyte GeForce GTX 1080 Windforce OC, 8GB - about 550€


Mainboard: MSI Z170A SLI Plus good or is there something better/cheaper? I need to buy it somewhere in Austria (https://geizhals.at/msi-z170a-sli-plus-7998-001r-a1325714.html?hloc=at)

PSU: What PSU would you use? I would prefer using one PSU instead of 2..

EthOS possible with Nvidia GPUs? I wouldn´t like to buy win10...

Hope someone can help me getting the most MH/s for 20k EURO.

BR,
Haris
