Does XP benefit from Dual-Core technology's ability to multi-thread and
other multi-core technology ???

If so, what performance changes could be expected over a single core CPU ??

You need SP2. Additional patches may need to be applied:

Dual Core is best for multi-tasking or applications that are specifically
coded to take advantage of it.

If all you do is surf the web and read email dual core isn't going to do
much, if anything, for you.

That's certainly the case and I don't think that any, even the
latest, MS Office programs have been coded to do it. It is not
that easy to parallelize an existing program and "improvements",
while real, can be disappointing. IBM pushed "Parallel FORTRAN"
20 years ago and had programs to analyse where improvements
could be made in code. I worked with it for a while but the best
speed increase I ever saw was about 30%.
