New Computer -- OS Trouble

I asked a similar question yesterday, but was unable to get a definitive answer. Hopefully I can make my scenario a bit clearer.

I plan to essentially build a new computer, although the only components I'll be changing are the motherboard, RAM, case, and CPU. I plan to salvage my hard drive, GPU, and other drives/peripherals into my new machine.

Now my question is whether or not I will need to purchase a new copy of my operating system. One suggestion from the previous post was to simply put the hard drive into the new machine without reformatting it and simply delete and replace drivers. Would this work, at all? or what would happen if I were to do a clean install?

Does anyone have any suggestions for what I should do?

Hey Peter, this is off topic but, I'm looking at these 8800s right? but theres the 640 and the 320, I only have a 21 inch monitor and I heard someone say that if your monitor is smaller then 22 inches, you only need the 320, but would there be any difference if i got a 640? Luchance221

lol way off topic and not quite sure why you hijacked this thread, but it really depends on how much you want to spend.

You can try deleting the files for your old mobo,but many have problems. If you have your O.S. CD just lie to MS and say that your Hard drive crashed and can you get a new number.

qft.

as long as the current OS doesnt have an OEM key, you should be able to reinstall at any time. I've reinstalled windows a few times with different versions of xp and i've never had any problems.
