Mining difficulty will go up by 22%. What is you plan to do with 741?
741 seems outdated for me, even thought I am sitting on free socket.

And anyone sitting on ACTUAL free electricity and not mining is an absolute idiot. If you have free energy, then what is your reason for not using a 741? You're not making back compete profit fast enough...?
