Jesus Chrysler people!!!! Dual Core is ONE THING, Dual Processor is ANOTHER TOTALLY DIFFERENT THING! You either reffer to it as you should, or give it a rest! If someone came to visit this forum just now and laid an eye on this thread especially on the few last posts, he'd immediately leave under the impression that most people here talk out of their asses and can't make the difference between two different technologies...
I've said it before and i'll say it again. English is not my native language, but i don't go around calling FireWire fireware, or even worse as i've seen in other places with tons of english speaking people, calling it firmware or some stupid crap like that. Get your facts straight! Read a little bit and then post like crazy. Sorry, but i couldn't help myself...
PS: Dual or Multi Core technology is used nowadays in modern systems. But multi chip systems can have multiple multi core CPUs. Have a look at the Mac Pro for instance. Get it?
And by the way, there have NEVER EVER BEEN ANY "dual core" PowerMac G4 systems. Dual CPUs, sure! The first and last PPC DUAL CORE CPUs ever used in Macs were in the PowerMac G5.
