I don't know about VUE, but I use Poser 7 with 2 Gb of RAM. That seems to handle two V4's in a scene with a background pretty well. I watch the system resources during my test renders, and I seem to be around 1 to 1.5 Gb during that period. I would think more RAM would help you significantly. By the way, both Best Buy and Circuit City have their more popular RAM on sale this week for about 1/2 price.
