Is the memory problem just a PC issue?

I actually haven't had too much trouble with the memory bug...unless I try to render. Even if I have only one figure in the scene, I cannot render at large size/high quality settings without the memory bug kicking in, and nuking the entire file.

And what happens is really weird. The file looks fine. The textures are all correct in the material room, the preview looks great. But try to render, and most of the textures are missing. No skin textures. No lash trans. No clothing textures. But preview mode looks fine. It's bizarre.
