I read somewhere that XP Home doesn't support dual core processors? Is this true? Or did it mean it doesn't support more than one processor on a board, but it does support dual core chips?

... probably the wrong place to ask that question.

though i would think xp should support DC procs by now because intel core duos and dual core AMD chips are available and have been for a while.

Here's what MS has to say about Hyperthreading. http://forums.macrumors.com/showthread.php?t=192370

Note: Windows XP Home can use a maximum of one (1) physical processor. However, because Hyper-Threading is supported, the operating system takes advantage of the second (virtual) processor.

I presume dual physical core CPUs are treated in the same way.
