I still haven't upgraded to winxp yet. I'm still in win98se. I have heard that M$ will let you upgrade things like videocards without having to buy a new copy of winxp, but what about a cpu or mobo? I figure M$ prolly makes you buy a new copy of winxp for those? So whenever you buy a new cpu or mobo or harddrive you have to buy a new copy of winxp?
