XP does allow the use of dual core processors. Most PCs currently shipping with dual core processors are using XP Pro (hope you have latest Service packs), but vista will will work better with Multicore

Moving DOWN to XP, while appealing in many cases, may not work as well as you think - you need drivers for all your built-in hardware for XP. If you don't have them, you may find things like your sound doesn't work... or your network... MAYBE you'll be fine, but you should be aware of these potential issues.
XP HOME supports ONE physical processor. The processor COULD have 8 cores... but only one physical processor.
XP PRO supports TWO physical processors.
2000 Supports TWO LOGICAL processors (a logical processor is a core OR a hyper-threaded Core that is seen as two).
I would suggest you wait 6 weeks and get Windows 7 and install that FRESH - NOT AN UPGRADE. That has MUCH better performance and several nice new features. AND it will almost certainly support all your hardware. Then, if you want, you can get the business or ultimate editions and use XP Mode (Virtual XP, which works pretty well for most things).
My 2c here... I was also tired of Vista's issues and actually downgraded to XP on a new machine. Not a good idea at all, it was actually much slower then Vista SP2, I couldn't believe it. I gues it was because all other software on that machine was new and XP couldn't provide all the features they needed. So here I am two months later, back to Vista and looking forward to Win7 which should be a straight upgrade. I think you'll notice the same thing, my machine was also a core2 duo /4GB RAM thing.

Yup. Windows XP can use dual core CPUs.
Depending on the chipset and CPU, you may experience decreased performance, although this is rare. There is an update available that fixes this problem. More info can be found here:
