CNET posted the requirements for Vista, straight from Microsoft.  There are the usual 2 lists, the minimum stats and then the recommended, or as they call it “Premium Ready”.  Read through to find out if you are ready, or if you need a component or two to get there.
“That said, Microsoft did publish official minimum requirements for Vista on Thursday, largely matching the Vista-capable specifications. Systems need an 800 MHz processor, 512MB of memory, a 20GB hard drive with 15GB of free space and a CD-ROM drive. That guarantees access to Vista’s core features, but not Aero and other premium features.”
