I was conflicted for weeks, going back and forth, about getting the new 27" iMac 2.8 Ghz Quad-Core with 16 GB memory or the Mac Pro 2.93 Quad-core with 8 GB memory (the jump to 12 and 16 is outrageous). I'm a student working with Maya, Mudbox, Blender, Vue, Adobe stuff, and Final Cut Studio. I would love to have a monsterous Mac Pro 8-core, a billion gigs of memory, and I seriously considered getting it, but...I settled on the iMac and money for a vacation to Hawaii instead of the Mac Pros. Was it the wrong choice? Of course, I chose the RADEON HD 4850 graphics card. But will I still have to wait days for 15 seconds of 3D animation at 640x400 resolution to render? Will the imac keep cool enough for this kind of work? Thanks for your advice!
