If I upgrade to a dual core processor, on the same mobo, will I need to reinstall windows xp? I'm really hoping to get around this ...

I don't think so. I *think* there is a windowsupdate patch that you might have to download after you swap your proc for the dualie and that is it.

I upgraded mine ok without reinstalling. Windows XP will detect the second core when you boot up and install the relevant files for it. A further reboot and you'll see the 2 cores listed in device manager.

You can download a driver for it from the AMD website.

MS now have a patch for people that have stuttering in some games with Cool & Quiet . I haven't installed this, but my 4400+ works fine in the likes of BF2 anyway

You shouldn't have to reinstall, but you may have to reregister your version of XP due to hardware changes. I think you're alloted 3 or 6 hardware changes before you have to reregister your copy of XP, otherwise it'll lock up in 3 days.

In Windows NT I had to reinstall. Since Windows 2000 going from single to multiple processor works without a reinstall.

According to AMDZone, you may experience performance loss using dual-core AMD processors with Cool'n'Quiet enabled on Windows XP SP2. Microsoft is reporting the problem in a knowledge base article, but doesn't let you download a hotfix, you need to contact them directly to get it... However, a patch is available from AMDZone, which improves CPU performances and addresses some Cool'n'Quiet issues.

Please read the instructions carefully if you decide to apply this patch, since you need to change registry settings also. That patch seems to be a beta one, and this is probably why microsoft is asking you to call. Use it only if you experience instability or performance loss, or if Cool'n'Quiet is not working correctly. A restore point should be made before applying the patch, just in case...

Thanks for the help guys. I've asked on AMDzone just to make sure, because right now, it's the main reason I'm avoiding the 3800+. I'll let you guys know how it goes.
