All depends how much poser stuff you want to load if you get vue, as even with vue 6 inf and even 5 inf, you can only put so many poser characters in before it crashes.
I have seen 6 poser people and scene loaded into vue 6 inf and ext from single, dual and quad core up to 8 gb mem on various comps crash out, if you want render large poser scenes in another 3d app dont use vue.
But if you just want use couple poser people some props just for render then vue is supperb but remember every other 3d app out thier can render poser scenes which ever way you bring in..
Vue will crash out of memory in a poser scene that every other 3d ap can render no probs.
