Curious, why have you been so all in on Nvidia and Zec all of a sudden?
Zec has a tiny market cap

Only 80 million
Nvidia has a market cap over 59 billion
https://ycharts.com/companies/NVDA/market_capAMD has a market cap of over 12 billion
https://ycharts.com/companies/AMD/market_capNvidia is clearly on-top at the game of gpu building and making profit.
Until Zec was created last year AMD was a clear winner in one area over Nvidia and that was mining coins.
I believe (no hard proof) that Zec was built for Nvidia so they could beat amd in some not all of the mining game.
Nvidia 1060 6gb vs Amd rx 480 8gb
the Nvidia hashes higher 320h vs 300h
the Nvidia uses less power
they each cost about 240 usd
So to me mining Zec using Nvidia is the way to go.
Note I never go all in

I mine at nice hash
i have about 4000 h in nvidia cards.
i have about 4000 h in amd cards.
the op really wants a 1 card miner as I read his post.
So I think he should do nvidia and mine zec. he could start with the 1060 and he could use nicehash to convert to btc instantly he card would pay off 100% in arounf 110 days.
he could sell it here for say 125 usd which would be 250 in roi with coin in 110 days the sale for 110 makes for a 125 usd profit.
I think no other card makes sense for him.
