Looking at the new iMac 5k for video editing 1080 and 4k. I would max it out as follows; iMac with Retina 5K display Hardware: 4.0GHz Quad-core Intel Core i7, Turbo Boost up to 4.4GHz 32GB 1600MHz DDR3 SDRAM - 4x8GB 1TB Flash (SSD) AMD Radeon R9 M295X 4GB GDDR5 Apple Magic Mouse Apple Wireless Keyboard (English) & User's Guide Storage: PROMISE Pegasus2 R4 8TB (4 by 2TB) Thunderbolt 2 RAID System http://store.apple.com/us/product/HE151VC/A/promise-pegasus2-r4-8tb-4-by-2t... Software: Final Cut Pro X Pages, Numbers, Keynote iPhoto, iMovie, GarageBand OS X Basically, I'm looking for smooth 1080 and/or 4k editing along with a UHD monitor. Actual final rendering output is not an issue. The maxed out iMac with the 27" 5k retina display, thunderbolt 2 storage and running FCP X certainly seems like it would fit my situation/use. I'm not editing raw 4K and/or using RED camera's, therefore I don't need a ton of processing power. My current equipment is as follows; Sony PXW-X70 using 10bit 4:2:2 with 4k upgrade on the way. Canon 7D DSLR I would like to hear from those of you that are currently using the new iMac 5k as I am planning to. If you are, could you give your thoughts, experience of the following? Your help would be most appreciated. Thanks in advance, Ray 1) How is it handling FCP X? 2) Are you running other software for example; Motion 5, DaVinci Resolve, etc.? 3) How is it handling effects, transitions, music, pictures, etc.? 4) Any lagging, hiccups, etc.? 5) Is it quiet enough to do voiceovers? 6) Any external drives? If so, how do you have your external hard drives configured along with what each one is used for?
