Latest version of my guide to building and operating a mining rig is here, How to Build a 6 Rig GPU Miner for Zcash and Ethereum with Nvidia GTX 1070 and EthosDistro posted Oct 1, 2017 on Steemit.
Nvidia miners work really well for mining Equihash based cryptocurrencies, like Zcash and ZenCash.
I have not had a chance to set up an Nvidia card miner yet, but if I do I will use either the latest version of Ethosdistro, which supports Nvidia cards now, or Ubuntu.
The ZenCash community is great, especially for mining. I was talking with one of the guys on there, @masterdubs, who shared a how-to for mining ZenCash with Nvidia.
His first post is How to set up a ZenCash wallet for Mac, which is helpful to get an address to mine to.
And his next post is How to Mine ZenCash on Ubuntu 16.04 with Nvidia GTX 1070.
