Opinions make very poor facts but I think that's the best you're going to get when trying to decide whether to go for the upgrade or not. I happen to agree with the two posts above. The Bryce 5 is worth the $99 CompUSA price. Trees, metaballs, and a way to render higher quality images: good. As for more/different material presets: no, not many. But the dials are still there ready to be twisted into a million different permutations of your own design. Not bad,eh?
