Well cult 7, I call a K6-300 with 64MB RAM mine.Your's faster than my CPU. Bryce needs long to render, but I thnk it's Worth it. Most of my Images were rendered over Night while I was sleeping and the Day after. Some Ideas weren't finished, because I didn't want to wait half an Hour for a 300x225 prewiew Render.What Bryce slows down are Materials with transparency and refracion.Reflections arent that bad. And don't use tooooooooooo many Lights.I think you should watch Bryce while you are working with it to get a feeling on what slows your System down - I mean Materials, Light and number of Objects (Polygones).If Bryce uses your Hard Disk often, it's better to get more RAM.Hope that you get other point of Wiews fom other Users.So you know what'the right Thing for you.
