I`ve just recieved the email below from pandaminer, the new pandaminer B5 will be having rx 460 GPU`s instead of the rx 480 GPU`s, this means that each will be having a total ethereum hashrate of around 90mh/s.   I also believe that the RX 460 hashrate is also affected by the increase in epoch. It seems that pandaminer is moving from bad to worse, this is a very bad business idea.
