I have a Dell Dimension 8200, build 97XJZ01, with a 2 GHz Pentium 4 and 512 MB or RAM, running XP Pro and I'd like to upgrade to a 64 bit capable MB and 4 core CPU, good/not necessarily bleeding edge graphics card for video/photo processing, run Windows 7 Ultimate, keep all the pictures and documents on my present hard disk and add a high capacity hard disk, and a couple of blu-ray drives. I think I'll go the retail route with Windows 7 for the support down the road. Can anyone point me to a "for dummies" step by step process for doing this in a relatively inexpensive way?
