The processors that are natively clocked high do not always guarantee higher overclocks, due to things like heat and the maximum capability of an architecture. Since they come from the same silicon, and the same architecture, it doesn't matter what the native clockspeed of a processor is; they will both end up relatively close to eachother. Just look at AMD's high-end processors; The FX-57 could barely overclock to 3Ghz, while a 4000+ reached the same speed. A X6800 may end up as much as .2Ghz ahead of a E6300, but you can't say that that's worth the $800 difference in price, while keeping a straight face. Basically, a 2.93Ghz processor and a 1.86Ghz processor aren't that different once you start to overclock them; one just costs 5 times the other. Natively high-clocked processors are for those that don't overclock, for one reason or another, or have a lot of LN2 to play with.
