Dear all, I 've been reading lots of posts around here and this is finally my first one. Also, sorry in advance for my english. I will try to keep as short as possible because my choice is already being long... I need a new Mac workstation within the next 2 months, with a budget around 5k (in Euro). My main jobs are: • video work with AfterEffects (no 3D compositing, just video footage, compositions and effects) • 3D modeling with OSX Rhinoceros AND Win Rhinoceros with Grasshopper (which is not available for Mac yet and painfully single-threaded) • rendering of lots of high-res images with Keyshot (OSX again) • (slow) 3D video renderings with Cinema4D I would choose between a fully-specced iMac (i7 4GHz) OR a 6-core Mac Pro. I would take 32GB of ram and 1TB flash drive. My main doubts: • Which is faster with After Effects rendering? Would the double graphics card be a plus? I have a quite old video card now where Mercury Engine is just grayed out and I can't find real-life benchmarks comparing the machines. What should I expect? • Which one has better viewport performance in Cinema4D? Occasionally (but not rarely) I have very large scenes, taking 2+ Gigs of VRAM. • Also, dealing with large files, is the iMac's SSD faster in real life? • I have a big concern about heat and noise: my rendering sessions often last 3-4 hours. In this scenario, would the iMac throttle, becoming slower than the MP? • If I choose the Mac Pro, is there any OpenCL rendering engine I should spend my time learning? What about OpenCL VrayRT under Bootcamp? • How faster could the 2016 Mac Pro be? Thank you in advance!
