My Poser 5 runs good on my 1Ghz, Pentium 3, with 128MB SDRAM. However, I just can't use dynamic cloth, or hair, and expect quick results. I was amazed how quick the Bryce engine seemed when rendering a landscape animation, after not using it for a while. And since I'm planning on making a full-length movie, with the hub of the movie rendered in Poser 5, I need this thing to crank out some animations, and I just can't do it captain with my system specs, if I want Dynamic cloth and hair. I need a dual Intel Xeon Processor, 2.8 Ghz, with 1Ghz ram, and a NVidia Card. This is what I want to get, I just need to save up a whole lot of money!
