What you're paying for is the guarantee that the CPU can make that frequency without overclocking it. All Core 2 Duos have pretty much the same limit on their maximum overclock, it's just that the lowest ones don't get quite so far due to motherboard restrictions. It's typically around 3.8Ghz I think before you have to have water cooling. humzaSM: All that's been verified is the frequency it made, not the temperature. It was probably phase-change cooled.
Looking at some of the over clocking speeds on the intel starting to wish i went intel rather than sticking with my trusted AMD.Still i have over clocked to x 2 2.67mhz now and for what i use my pc for that's plenty.The design of the newer motherboards now are all set up for overclocking with pipes all over them for extracting the heat so there is no worry about over heating the cpu if your sensible with your system.The other advantage of the intel which i have noticed looking at the intels is most offer a larger cache size than the AMD so at present intel is the way to go until AMD fight back which i'm sure they will.
Yeah exactly, I'd still be content with my X2. As for that screenshot, it's the best revision, but that's exactly it, whoever got that CPU was VERY lucky, most of them aren't quite as good as that. I can believe that the specific batch he had made 4.2Ghz on air, but I don't believe the temperature you told me. I'd reckon fully stressed under load that'd make high 50s Celsius at least.
