What do you consider low RAM? I say yes the more RAM the better when using one or two displays, especially in an OpenGL environment which is what the Poser previews are, if you have more RAM on your video card you wouldn't have to look at those box shaped characters when moving their extremities. There are a lot of decent video cards out there with 256 MB of RAM for about $50. Can you put a link up on what exact video card you're looking at?
