i5-750 vs P55 vs water Currently @4.4ghz!

Also depends on how long you plan to keep it. Cpus have a finite lifespan even on default voltage, and increasing the voltage will shorten it due to electromigration, even if it's kept at cool temperatures. This is a fact, not a probability. Whether you plan on keeping it long enough to care is a different matter.

Kinda does make some sense

But I think this theory also goes back to the particlular CPU being overclocked. If you got one that wants to run and seems to scale pretty well then you have a greater chance of success. It's when one pushes the cpu with massive voltage increments to make the next jump that the risk increases.
