I started my 3D journey on Ray Dream 3 or 4! That is how I came to Carrara2 Studio. On another monitor on my right there is a GI render running that I will upload tomorrow, I think. If you have the resources, it is a nice step forward. Strangely enough one thing I liked about Ray Dream did collapse: these days Boolian actions gets you artefacts I do not remember from using Ray Dream. Do NOT throw away that copy when you upgrade. I actually earn some money with the output from Carrara (and VectorStyle incidentally). Including flash/illustrator stuff. My new firm actually has a house style that would not exist without it.
