The more you have of everything the quicker Bryce will be. I've just upgraded my machine to a Athlon 3.0+ CPU and have two 120Gb hard drives, one to hold all the programs and the other to store all the models, texture images, and Br5 files. I've also got 1Gb ddr ram, I did have 1.5Gb ram but I've now set up another machine that is totally dedicated to rendering and it got the other 0.5, which is brill especially if it's one of those renders that's going to take days. My latest render is on it's third day. 8) Catlin
