As has been kind of mentioned already, the key things for increased speed in Poser are: 1. Processor - a faster processor is the #1 thing to increase speed 2. Memory - the more memory the better. For graphic apps, 256 min, 512 is better. Depending on your operating system - try WinXP (if you are an IBM person). It has fantastic memory management (for a Microsoft product). Downlevel MS operating systems (WinMe, Win98...) have limitations to what they can do with memory above certain amounts. 3. Operating system (see above). 4. Hard drive - if you have met all the above criteria, you can honestly do without SCSI. Rendering is done in memory by the processor. You only really go to the harddrive when reading textures/files and saving images. It will not produce any real noticable speed increases.
