Quote - Ya..I'm on XP and will stay there until I'm convinced. The only thing I will say, is the fact I'm on what is now almost a dinosaur system which I built nearly 4 years ago, with an AMD64 CPU...which has never seen a 64bit OS running through it.  Its a shame, really.

Are there that many 64bit programs available? Does it even matter at this point ?

Sure there are... Vue, Cinema 4D...

While not a 64 bit app, Photoshop CS3 will take advantage of over 2 gigs of ram in a 64 bit system.
