I'm running almost the same system you are except I've got a 1.2 Gig processor and 310 meg of ram...(Yes I know that's a weird amount, but I got a 64 meg stick for free when I bought the 256 meg stick) Same Video card. I'm running Bryce 5, which renders slower than Bryce 4 (In my experience) Looks and acts great though. Haven't had any vodeo problems at all! Great upgrade from my P3 600...
