can I keep original setup if I change my CPU

[Firestarter666]

I want to upgrade my processor to an AMD dual but I don't want to lose any data or the programs I have. The XP o/s I have loaded is an OEM version and so cannot be reloaded. If I just change over the processor with a new one will everything remain the same or will I have to start from scratch?
If I do have to does anyone have any recommendations to upgrading to XP64.

I am hoping to just be able to buy the new dual CPU and plug it in and carry on as usual but just a little better in performance.

ANy help or advice would be greatly appreciated.

Can I just check that you are saying I can just change over the processor and all should still work ok as long as I download a Dual core driver 1st.
I want to stay 32bit for now until they launch the fully working version of 64. I have a creative soundcard too which I know the 64bit platforms do not support properly or at all. I have a lot of programs and files on my PC and it has taken me ages to get it all set up and running the way I want so I don't really want to have to do a clean install and start all over again.
