i think dell will regret this when they reazlise that amd are on the whole more prone to go wrong than intel.
dell customer goes and decides to get a nice memory upgrade to his amd rig, oops corsair doesnt work with his shiny new cpu, but does he know that? nope.
another issue will be motehrboards, intel mobos are not overclockable, and damn right boring, but rock solid no doubt. I wonder which mobos dell will use in their amd rigs, because whatever they use, someone somewhere will have problems.
