Can Windows XP run with two processors?

If you mean dual core processor the answer is yes.

With the release of dual and even quad core processors putting the near equivalent of as many as 4 CPU's into one single ship having two separate CPU chips is no longer worth while in all but the most high end rigs.

Old versions of Windows XP Home didn't support multiple processors, but with the Service Pack 2 update, you can. Windows XP Professional has always supported multiprocessing, if I remember correctly.

If you're speaking of a 'duo core' processor, which is essentially, two processors, then yes. However, hooking up two different, separate processors, can be done, but it costs a lot of money. Macintosh computers automatically come with two Quad core processors (Essentially the equivalent of having 8 processors). I suggest doing a special search, or going to your local computer store/chain store, that will help you build a custom computer, and asking them.
