anything over 1.0ghz and 256mb ram will run vista
the areo glass witch is gonna cost extra will require
an 128mb video card plus a few other goodies
the most important windows vista is going to be direct x 10
the specs for direct x 10 haven't been realeased as far as i know
so in short yes it will run vista will you be able to runn all the apperance goodie probly not
if your interested in running vista wait till it comes out before you build a pc for it
