@markosky just use the nicehash profitability calculator (https://www.nicehash.com/?p=calc ). Select your gpu or the gpu you are looking to buy. It will tell you how much power the gpu will use, what will be it's hash rate, What will be your Return on Investment (RoI), your profit and how much you will be making on daily basis
Hope that helps :)
Thankyou @kartikbholla
I tried to look for my hardware....LOL. I don't have anything like those expensive requirements.
I have an I7 950, 12GB ram, 2x amd 5770 in crossfire. It plays my steam games on windows just fine, and linux of course its a beast. So why is it so hard to mine with old hardware ? I would think it would be just the opposite. This is my first post in the community !
