You do realize, of course, that CPU mining is no longer profitable
ever, regardless of CPU model and local cost of electricity. You pay a premium over what a BTC would cost if you just bought the thing on Mt. Gox. Maybe 30% more, maybe 50% more -- maybe even double!
Do mined BTC taste better than ones you buy from an exchange?
I guess you're probably setting this up on your work PC -- still, I'd be careful. Making 0.3 BTC a month (current value: $0.87) isn't worth losing your job
