Do I have to reinstall my Windows xp home, if I change my core 2 duo e6600 processor to core 2 quad q6600?

Should be plug and play.

If I was getting a new Q6600, what I'd do is.

1) With E6600 still in place, go to Device Manager, check the
computer entry, make sure it says something about ACPI
and multiprocessor.

2) Shut down, install Q6600. Boot up. The Device Manager should
still show the same ACPI and multiprocessor for the Computer
entry.

3) Run Prime95 multicore version. Open Task Manager, check the
four CPU performance charts. Are all cores running full blast
once Prime95 is running its tests ?

You can get Prime95 multicore version here. When it says "Join GIMPS?"
say No. You can leave the defaults in the custom setup dialog, and
then run the test. With the Q6600 present, this version of Prime95
should start four threads of testing. With the E6600, you'd see
two threads of testing.
