In our shop we are rending animation. We have dual opterons. We render 
with the 64 bit version of mental ray. We did side by side tests and found 
that the larger and more complex the task is the more savings there were, 
but when rendering a bunch of small simple files the savings were not 

On the very complex shots we cut render times by almost half. Most of our 
jobs are not very complex so the ratio evens out at about roughly a 10-20 
percent gain. But the thing is that when the time comes to do something 
very complex comes it can be finished in say three days as opposed to five
