That is about 130 Mhsh with 70% power limit not at full power or around 170 watt for a card or 510 watt for three cards.The price of cryptocurrencies are going down like crazy but here is the catch,it is in such situations that decide who is going to be the winner,a winner for me is the person who keeps mining even at a loss and are thinking for long time profit,if you are for such use case scenario go ahead and buy the cards,if you are for making a quick buck refrain from buying the cards.
