NO! I got it and cannot use it. There are some old objects I have that KILL the program along with my computer. I was having to save every 2 seconds. When it did blow up.....and it ALWAYS did....I had to reboot my computer, uninstall Bryce 5 and then reinstall it. I kept calling support, they said I didn't have enough ram.....I have 768 ram! PLENTY! My computer was BUILT to be a graphics machine! I am now using Bryce 4 again, feeling the sting of $150 blown out the window!!! Mind you, this is just MY opinion, but other people have been having similar problems! I would see if you can try it out first.
