Sounds like a good system to me. I have a 900 Mhz AMD Athlon 384 MB RAM Geforce2 MX 64MB card 17" monitor If you really want to try a different system try AMD chips. They are cheaper and in a lot of cases faster than the same P4 chip though they do run hotter. Other than that I see nothing wrong with the system you have. CPU power is main determination with render speed in Bryce. Only way to speed it up is to get a faster CPU and/or network render with Bryce Lightning (if you have Bryce 5).
