To me, it's not worth the hassle of dealing with Microsoft and all of their fine print technicalities, so I will not be transfering my XP from my Dell to my new build. However, I was just online with a Newegg agent who told me that there was not a requirement for me to purchase an additional hardware product when buying the XP OEM. I placed the order and it went through clear and free.
This is a complete new build from the bottom up, so the OEM will be tied to my Asus mobo, which is fine beccause I am not planning on completing an entire new build for some time. So, everything is on the up and up and is totally legal.
My question is, will there be a difference between the OEM version I just bought and the over priced $200.00 version??? Outside of being able to install it multiple times.
