I have a 3000+ winchester skt 939, do i need to reinstall windows, or is there a way around that if i'm moving into a X2 chip with all the same hardware.

You may just have to do a windows repair. It keeps programs and documents, but reinstalls system files to your new hardware specs.

i have heard from ppl that WinXp Home does not support dual core procs and that if you want to run both cores you gotta use WinXP Pro or "hack" Xp Home...is this true?

I have XP pro and when I switched from 3500+ to x2 4200+ I did not need to repair or reinstall windows.Seemed to work fine for me. I have since done a few more changes and reinstalled windows and can't tell any difference. As a general rule, when making a major hardware change a reinstall is agood idea

Home only supports a single core.

Back to the subject: Try right clicking on My Computer and selecting Manage. Then locate Device Manager and open it. Right click on the computer name at the top and scan for hardware changes. It SHOULD auto-detect the new "ACPI multiprocessor HAL".

Let me know if this works. It's a theory.

You will be fine going from a single core to a dual core without reinstall with windows XP pro.

So, it's full auto-detect on reboot?

It was for the guy I traded my 4400+ to. I didn't reinstall and his 3700+ worked just fine.

That isn't even needed half the time.
