Vue 4 and 5 will import Poser scene files. You do not need Mover unless you want to import dynamic cloth and hair, or Poser animations. E-on offers demos of all their products. You can try before you buy, to see if you like it. I haven't had memory issues with Vue. IME, it will easily render scenes that Poser never could. DAZ|Studio doesn't work well for me. Some people say D|S renders scenes that Poser chokes on, but some have the opposite experience. Like me. I've had D|S crash when I try to render a scene with just one V3. (Might be my video card. I have a Radeon, and I gather D|S prefers Nvidia.)
