Hi Hive account@outerground, you're partialy right. As you noticed, my graphic card is far from being "the latest big thing !". I use this computer to do 3D renderings for clients. It's been a long time that the whole computer as been amortized. So all the money i get is extra-money. I've settled this last year, and all the earning covered more than the price of the machine at the time (the bitcoin was 400$ at the time). All in all it has been more than profitable for me. Plus i keep the bitcoins, as explained. To be true, i also didn't count the extra power needed to make these calculations. But it's still profitable. My MSi graphic card works at 70% of power, 80°C top since february 2016. The real problem is the heat it produces while working...
