I mined xpm when claymores miner first came out, but it requires a pretty beefy cpu otherwise the gpus wouldnt load. I upgrades my semprons to 6 core fx's and mined their cost back, about then xpm difficulty rose too much so i dumped the fx's and went back to semprons.

My question is why is network security considered a waste of hash power? This is like saying oxygen is wasted because we primarily use it for breathing.
