Op's PC isn't profitable but as a learning experience it does pretty well.
I have several 6x and a few 12x rigs and they're just barely profitable these days. I haven't really looked into better coins to mine though.
It's definitely an interesting hobby with a lot to learn from it, but not a profitable one.
