I currently have an Athlon 64 2800+ in my AlienWare desktop that I just recently managed to get working again. I've already decided on a new video card and HDD. But I'm new to the process of putting in a new processor. The current socket is a 754, and the one I was looking to get is Socket AM3. I'm not sure if that will work or not, will I have to find a Socket 754 processor, or get a new motherboard all together and transfer the components? One more thing, if I replace the processor will I have to re-install XP? Or is that only if I switch HDDs?
