New Motheboard and Windows OEM

[wrl-x2]

I need to install a new Motherboard in my PC due to overheating issues.
All the existing hardware devices i.e. CD-RW, Graphics Card, Hard Drive etc.
will remain the same. If I purchase a new Motherboard and using all my
existing hardware, does this mean I have to purchase a new copy of Windows XP
Professional or can I re-use my original copy (which happens to be a OEM/Non
Branded CD).
