I once tried to apply displacements to 2048 terrains. To my surprise, Vue ate all my 8 Gigs of RAM before crashing. In this case, having 12 Gig would not have helped.

For the scene in this tutorial, I first wished I had more RAM. I then decimated the Poser characters (which are barely seen) and removed the complex ecosystem on a large background terrain and it was much easier to handle afterwards.

In my experience, only scenes with large ecosystems and numerous imported meshes can make me hit the limits of my 8 Gigs or RAM. Also, launching the external renderer while a large scene is still open in Vue may make me hit the litmits.
