I agree with Who3d. I went from a P3/800/512MB and 20MB HD to a P4/2.6 with 1GB Ram and 240MB HD 12 months ago and don't regret it ome bit. The bottom line is that for small Runtimes and simple scenes it is a lot faster, however you can do a lot more with it as it doesn't choke on on 2 Millenium figures with large textures any more. My Runtime is now 40GB and it does take a long time to load but I can have lots of figures and/or better lighting and I don't have to downsize texture maps any more. If you want fast loading and renders just do one figure/prop at a time and composite the pic in a paint program. I mainly use PP and ocasionally use P5.
