Picking up a processor and overclocking it until it is just short of melting is a definite way to get more value out of your PC.  Why pay $500 when you can pick up a $300 chip and get it to go just as fast as the more expensive one?  X-Bit Labs thinks there might be a hidden cost to your overclock though.  More power translates directly into more power, especially if you are playing with your processors VCore.

“Processor power consumption is closely connected with their clock frequency. That is why when overclockers increase their system performance they sacrifice energy efficiency. But how serious this problem actually is? We tested nice different processors from Athlon II, Core 2, Core i3, Core i7 and Phenom II families overclocked to different levels and are ready to give you an extensive answer to this question.”
