Taking my first step into Bitmining tonight and it seems GUImining is serving as a roadblock for me already. So far my total progress is a crash on launch.
Right now I am making use of an above average laptop while I try to get my foot in the door and learn how this all works. The graphics card it sports is a Radeon HD 7470M with a i7-2670QM hyper-threaded quadcore on Windows 7 64bit.
I am unsure how "efficient" this machine will be and at the moment I am more interested in getting the software working before debating the hardware.
