Quite impressive. I've been looking at R9 Nano and Fury as I'm also interested to build a machine for Virtual Reality. Mining with such specs seems very promising to offset the building cost. How's your energy consumption? I guess the solar is only for day time and only count for part of the power supply?
But I have studied about solar energy, and read about batteries .... and here in Brazil the sun is intense. From what I know of this crypto currency are not being released in a different way has the best programmers of crypto coins, and know it will be worth the investment.
Agreed that it will be worth the investment. In the long run, energy will be the main cost. As for now, I'm waiting for price drop of GPU cards as the release of more VR devices and contents.
