My understanding was that they used 2.8v for core logic and 3.3 for interface logic. That way, you get the power/heat advantages of a lower voltage part without having to redesign the interface chips to handle the lower voltage. You'll notice on "MMX ready" motherboards that there is always at least two regulators. Maybe this is clearly understood by everyone but no one actually said it... -- David W.
