I've had my X-1 for about 4 Weeks. I have been mining at 1100Hz since then at about 110Gh/s.

Getting any kind of ROI.. I don't think so , so all the income I'm making I'm putting into buying ghash.io and I'm up to about 20Gh/s extra via ghash.io at the moment. Maybe in 3 months time I'll be up to 200Gh/s in Total and I'll sell the X-1 and put it towards more Gh/s

But I'll still be behind for quite a while :-(
