I run Vue 7 with Vista 32 and have 3GB of ram, I work with massive scenes and do not have any OOM errors. Not sure what must be going on with your machine, are you sure its configured correctly? So I can't really support the you need 6 to 8gb of ram argument as it doesn't hold true for me, even with scenes with billions of polys and multiple eco-systems.

Or maybe I am just lucky :)
