I want to build a new computer and use xp for the operating system. If I build the current super computer will xp run ok on it. Money is a problem, but I could always upgrade to windows 7 later. I am running xp on a computer I built with amd athlon xp 2600+ processor that is over 8 years old. I really like xp and have some old programs that I use that will run on it just like they did on win 95 and 98.Thanks
