New CPU

Do I need to change anything in Windows XP now that I have upgraded my processor? All the other stuff in the system is still the same (motherboard, memory, cards, etc). This new CPU is the same series as well, just a better model. Other than having a somewhat faster clock speed, it also has twice the cache. I just want to make sure Windows is getting the most out of the upgrade. I just recently formatted, and I'd rather not do it again for at least 6 months (I usually do it annually).

Oh, and in before "install Linux", etc, etc.
