Break-even is 0.2 cents/hour per core for a 4-core system that uses 100 watts. A full i7-3770K system with integrated graphics uses 102 watts under heavy load [1], and when each of its 4 cores sells for 0.2 cents/hour, that covers the 4*0.2 = 0.8 cents/hour difference from natural gas to electricity. 0.3 cents/hour covers the entire electricity usage, providing free heat.

Okay, if it's per core-hour that's different.
