Hi - I produce a very wide range of motion graphics, all in After Effects (simple corporate infographics to highly complex particle-based stuff for music sync). I bought a maxed out iMac a while ago (5k, 4.0ghz processor, 1tb ssd, 32gb ram) and was largely unimpressed when compared to my aging macbook pro (2012). The iMac was consistently 30% quicker in a wide range of tasks (RAM prev and render); but that couldn't justify the expense so I returned it. I'm now looking at various mac pros, but I keep reading that processor speed, not multi core, is most important. The iMac had a super fast processor but wasn't impressive. I set it up according to all the best advice etc. If I get an 8 core mac pro 64gb ram, 1tb drive etc. will this help? Don't want to jump ship back to windows as my music tools won't work. Thanks!
choosing a cpu with faster cores vs more that are slower, would be preferable, but your options with picking a cpu is limited in the mac machines. you can look at this benchmark website to see how the various mac's stack up and choose what kind of performance you might want over your old imac or macbook pro.
Mac Benchmarks - Geekbench Browser ( click on the "64-bit multi-core" tab)
So, what was your choice finally ?
