So I am running Poser Pro 2014 on Windows 7 Pro, with an I5 processor and 8 GB of RAM and a 4 TB hard drive. I don't remember the specific graphics card, but it's a middle tier Nvidia card.

Recently I made probably the largest and most complicated scene I've ever done: a warehouse filled with containers, pallets, loose wires, boxes, shelving, etc. There's probably well over 100 objects between figures and props.

This scene is basically killing my system. It takes close to 5 minutes to load the scene, the preview window is very slow and jittery, and it takes roughly an hour to render one image at 1600 X 1200.

I know the render times are directly related to my processor, but I am wondering what speeds up the preview window? Is that also processor based, or is it more the RAM or graphics card that would help with that?

And what about scene load times? I assume that is purely related to hard drive performance, and maybe RAM, but has nothing to do with processor speed? I'm saving the files in compressed format, so I know the scene has to uncompress to load, but 5 minutes seems like a very long time to wait before Poser can actually be utilized.

I'm planing some upgrades, but I'm just wondering what will provide the most bang for my buck because I'm on a budget. Otherwise I'd just build a whole new rendering rig from scratch.
