I have recently built a rig consisting of 4 x XFX R9 290 to mine Doge coins. The cost of the rig was around $2700 after getting an i3 CPU (socket 1150), 8GB of memory, and a motherboard that can fit all four cards. The value seems unpredictable as it fluctuates drastically on a day to day basis.
What do you all think about my setup? Will it make me any money in the future?
