This week I've mined 0.2 Ether using mostly just one computer with an Nvidia 1070 graphics card, but I added a second one just a couple of days ago with a 1080 Ti. It's my first week of mining since 2014 or so, (I used to mine some PeerCoin and PrimeCoin back in the day).
It may not sound like a lot, considering power use and all, but with the current market price it's worth around US $34. That's pretty good for a week's worth of mining in my opinion.
I know it may fall to half of this soon, but I'm going to keep mining Ether for a long time and keep them or convert some of them to Bitcoin. I'm long cryptos!
I will post updates on my mining progress as I reach new milestones.
