So i wanted to buy an rx 570 for mining, i know one rx is not enough but i will be adding from time to time. So that rx 570 has 28 - 31 Mhz on etherum mining and my computer consumes in total up to 300 watts, and in my country aka greece each the kWh price is 0.60 euros (up to 70 to 75 cents). Would i have profit by mining with my i3-8100 and that single rx 580 but overclocked?
