Ok, cagando se aprende.
BTW y una explicacion del porque las Nvidia son tan malas ?
Edit:
That, in a nutshell, is why GPU's can mine Bitcoins so much faster than CPU's. Bitcoin mining requires no decision making - it is repetitive mathematical work for a computer. The only decision making that must be made in Bitcoin mining is, "do I have a valid block" or "do I not". That's an excellent workload to run on a GPU.
