Although i knew that my graphics card is far from efficient, with a bit of tweaking i now managed to get 420 Sol/s in Equihash/Zcash, at 234 watt. Together with my intel 6700K processor mining Cryptonight/Monero at 4,5Ghz and my old GTX 750 card mining at 46MH/s Lbry/Bitcoin, I make 6 euro's a day on avarage.
My goal is to expand my number of graphics cards to 6 GTX 1070's , because the AMD RX 4xx and 5xx are all sold out. The price for a descent card is 420 euro's, so i need to mine for 3 months with my setup to have enough satoshi to buy a GTX 1070 card at Amazon.de with bitcoin vouchers.
After this upgrade my next goal is to buy the components to build a seperate mining rig. Because of the mining, gaming stands on a hold at the moment, to maintain the current pace. If i'm lucky, i can use the motherboard from my previous computer. But that is for later concern.
At this moment i earned 0,041 BTC by mining on NiceHash. I started June 1st. With the fluctuating BTC price its hard to determine how much BTC i need to purchase the GTX 1070, but it's estimeted around 0,18 BTC (based on a Euro 2400/BTC price) Because i started with only my GTX 980ti in the beginning, my earnings started from 4 euro a day to a 6 euro a day mining after i added the cpu and the old card in. So the already earned 0.041 BTC seems short to become 0.18 BTC after 3 months, but it will be, because of the added stuff.
