Thanks for the input. willf - perhaps the demo of c3? If not, thats ok. Gabriel - Its looks like the dual might be the way to go. I can assume it can only render faster on a (2) 1.25. I did the scene on my 933 iBook and got 8:25 as my render time. Anyone else with macs and c3, id love to hear your results with any configuration using the default render settings of "milk" Regards to all E.
