Excuse me, i work in designing & making films feature for television. My company intends to develop the 4K videos system in near future. So, i need a solution for MAC system which supports designing 3D, render film and exporting to 4K standard quickly and exactly. As i know, the Mac Pro system models manufactured before 2010 built with many CPU, many slots of RAM, and many slots of hard drive (so the hard drives can work in RAID mode, can't it?). But since 2013 models and later, the Mac pro only support 1 CPU, 4 slots of RAM, 1 Flash memory. I found those solutions on the Apple Homepage today, but i don't know if those support for my work well. So i have some question, please answer me: 1. Do the configurations of Mac Pro on Apple page support for my work well ? Which supports well ? And which supports best ? I need it doesn't cost a lot of time of my work. 2. With the Mac pro Systems on Apple page, only one CPU Intel Xeon E5 with 4 cores, 6 cores, and 12 cores used. Can i make a system with many CPU work together as the Windows Workstation system? What is the fastest speed of each CPU? 3.How many slots of RAM and how many Gigabytes does the Mac Pro mainboard supports ? The speed of RAM bus ? 4. Mac pro uses Dual VGA AMD Fire Pro D300/D500/D700. Do those VGA support for 4K video excellently? Is there any VGA supports better ? 5. Nowadays, can i use many hard drives or SSDs on one main board to run in RAID mode as Windows Worstation? How many slots of hardrive or SSDs does Mac pro support ? Many thanks !
