I really can't understand how you come up with such numbers. I'm mining from the launch with a 270x and a 280x. All i have managed to get from mining on dedicated and xhash pools, is 0.06 sync, up until yesterday when i gave up. From those 0.06, the 0.02 were mined in the first hour... My total hashrate was 3.7mh. 0.06 sync with the current prices is 0.03btc.
