No, it doesn't. The DAG is too large for a 970 to produce those numbers. I have owned a 970, The statement is false.
My rigs with 4 x 1070 are making a total of $2.5 per day, dunno from where did you get those figures. You will not even break even with free electricity. As for the price, It seems fair but could be lower. Do keep in mind people will assume US market rates here so if you are outside of US this might be a good deal for you.
Would you mind finding me one with specs like the OP posted?
