Many thanks Cybermonk and dmtyler for the given results! dmtyler, are you rendering with anti-alias on? I think that your render going faster than a P4 1.7 Ghz is not as expected ;-) I would estimate that, since your processor is double the speed of mine, your result should be something like 1 min 40 sec (half the time I needed), about 25 sec longer rendering time than the P4 (which is not bad after all for the P3!). Maybe if more people entered this test so we get more results to work with ... Now I am really getting curious for the double processor configurations.
