It might be time to upgrade your ethereum rig to more energy efficient cards. I have a r7 370x running full speed and the card only takes 80 watts full power.

Investing into Steem Power would be a great idea if you are planning on being in the community for the long haul. I also have a couple ethereum and have contemplated buying some steem power. It would probably be a good idea, as I love writing, and am completely interested in the potential of this community.

If the calculator is correct, I am excited that the numbers are looking very healthy. With luck and a lot of work, I will be able to earn some extra Steem with my postings and eventually when I get Steem Power.
