You have a good enough system for Bryce 5. If you're going to get into animations in Bryce, then a few other boxes on a network wouldn't hurt (Bryce lightening network rendering works great for animations). I have: amd 2.1 asus A7M266 half gig ram (need more) ATI 8500DV all in wonder card 450W power supply (often overlooked by homebuilders, a decent power supply is important) Win2k SP3 (best OS ever made by MS IMHO).
