yes, that's all, 31 MH/s is why i wanna buy it, and the question is up, so your turn.....
If you buy this graphics card to make money, but write the cost of electricity and the purchase price. I will also tell you that not all video cards mine consistently 31 megahash.
For calculation use 27-28Mh. For a short period of time, you can achieve 31 megahash, but after a while, the mining farm crashes.
