AM may sell less efficient chips but at least they are delivering. I was able to get my refund from MS and have the AM machines shipped and have been hashing for 2 weeks already. If I had waited for you I MAY have seen my order buy the end of August.
We have been delivering ASICs for the last 3 months. We have offered 6x more hashing power in the form of ASICs as replacement for X3. If you can use chips you should have chosen this deal.
