Based on my experience:

P5 will freeze for a lot longer than P4 when it can't find a texture or other file. It will sometimes lock completely requiring ctl-alt-del.

If you use more than a few characters and/or props, P5 will bog down much sooner than P4 and you'll begin to experience some very quirky camera behavior. Also, firefly will become useless, rendering most of the advantages of the Material Room also useless.

Advantages of P5 over P4/PP:

1. Multiple runtimes
2. ummm... My system: Dual pentium 4 1.7 xeons 1 gig o' ram 350 meg hard drive space / 250+ free
