Just to add my two cents... I'm on a Mac as well and Vue does make use of my both CPUs while rendering a still (G4 MP500). But I think it also depends on the OS Vue is run under.I did a little test with my latest image and rendered it with the same size (1400x2100 px in broadcast mode) on my mac and on the pc in my office (AMD Athlon 2.16 GHz with 256MB RAM). The pc needed only half the time (8.45 hrs). But it's processors is about twice as fast, since my mac is nearly 3 years old. ;) To agree with the others...get as much RAM as possible and if you can afford a double-cpu machine get one. To forester: I have to agree that Vue runs better under a pc, but you shouldn't forget that Vue runs on pcs for quite awhile. The mac version exists since version 4, so there's still hope. No need to say, that there are new chips for the mac around the corner which might blow away the new pcs someday... ;P Yes, I'm one of those macaddicts. LOL. Best regards, Phil
