Hi guys, I realise the iMac vs Mac Pro question gets thrown around daily, so I apologise for bring it up again. But there is a ridiculous amount of conflicting information online, and after literally hours of research I still haven't come to a definite conclusion about which computer to buy. I am a full-time videographer/video editor, and basically I'm tossing up between a new Mac Pro (base model, maybe 6-core) or maxed-out 27" iMac, and I have a few specific questions that hopefully someone can answer.... 1) For basic video editing (by basic I mean documentary type work, so not a lot of effects) do the GPUs really matter much, or is it mainly the CPU that does the work? 2) When doing lots of video rendering, would the Mac Pro's main benefit be its ability to run cooler for longer? The i7 iMac gets very hot which is worrying in terms of its life-span. 3) Will I notice the difference between 4-core and 6-core in general non-CPU intensive tasks, or is it only rendering that will show a difference? 4) Can someone please make my decision for me and tell me which computer to buy Thanks in advance.. sorry if these have been asked before.
