Peggy, this depends of course a lot what the image content is. And the Cow nodes too. I mostly render in the network - especially when i expect render times bigger than one hour.

A while ago i tested the farm of a friend and sent him a scene that rendered on one of our Windows machine in the office 120 hours in Superior. Lots of blurred reflections and dof. He has 10 really speedy nodes. He rendered it in Ultra and i got it back after a little less than two hours. I was impressed! :D
