Note that 32 bit systems can run 4 gig (with WIndows tweak). but each app cannot use more than 2 gigs RAM.

You have to have a 64 bit OS,and an app that is truly 64 bit, to get all the use. Otherwise the app will only use 2 gig, and rest be used for WIndows and other apps.

Vista Ultimate will install non-64 bit apps into a seperate program file folder.

Example: Photoshop CS2 is 32 bit, but, because of some tweaks in it's code, it can use a full 4gig of ram if you have it on a 64 bit machine, but it is not a 64 bit app.
Confusing, lol

Vue is 64 bit, Think Rhino is too?
