Not sure how much it cost to run ASICs, but I have a 5 GPU rig running RX480s and the cost is roughly $175-$200 USD per month. Which is killing me. Hoping Ethereum price goes up in the near future.
Seems like your setup is not optimized at all.. I have 7x gpus and paying $100/month for my rig. Feel free to shoot me a pm if you'd like to discuss
