[citation][nom]freename[/nom]Why would they bother adding more performance per $ when they're essentially competing with themselves in the top performance levels? All they'd do is stop someone with OC'ing know-how from buying a more expensive chip.[/citation]
Just because the 975 has an unlocked multiplier doesn't mean everyone who bought it was going to use it for overclocking. The fact of the matter is, when a 920 ships it's only guaranteed to work at 2.6 Ghz. Some chips will go much higher, and other won't, but that's not intel's problem. If you were building something that you wanted to be sure was stable at 3.333 Ghz, you could take the chance with an 920 and void the warrenty, or you could spend the extra money for stability and some peace of mind on the 975.
You or I may not care as much, but then again, very few of us were going to be buying a $1000 dollar processor when we could get about the same for a third of the price. Point being, most of us aren't going to be spending that much on a processor anyway.
