Me i am using a dual P3 866 with 512 mb. I always use 1 instance of Bryce, the other one is Bryce Lightning where i can use the power of 3 processor for doing images. (the other is a P3 550) And i have loaded with Bryce, CorelDraw, Photopaint and more... But Eric is right, because if you render and decide to work with another and the size is big... you have a possibility of having a slow computer. Pleiades
