Greetings and salutations, I've been racking my head for the past week about getting a new mac. I'm a youtuber and I put up nearly 2-3 videos a day sometimes on my Non retina MBP 2012 with no upgrades. Its been 3 years and as I expand my channel and I'm starting to think about short films, music videos and more, I am in the market of a new buying a new mac. I want to eventually work with 4K but for now 4K on youtube unless its a short film seems overkill. I'm a noob when it comes to mac buts from what I researched I need RAM, Fusion Drive, Strong Graphics Card and a strong processor. I really want to cut down on the editing, rendering and exporting and increase my work follow. I've also read that I should be editing on an external drive so i considered the G-RAID Thunderbolt. After researching, the iMac I want to configure looks like this: -Late 2013 non retina iMac -i7 Processor -16GB RAM (Maybe 24GB?) -1TB Fusion Drive -NVIDIA GeForce GTX 780M 4GB GDDR5 (Is there a big difference from the 775M 2GB) -I'm considering getting a G-RAID Thunderbolt 4GB* I also have Logic Pro, I do gaming videos using the elgato, I have mixing programs. I want to keep everything under $3000 if possible. I don't want to buy another mac for at least 4-5 years, I figure I can buy a 4K-5K display if I did video in that quality. I'm really lost on what to do. Do I even need an iMac or could an external drive fix my worries. Any and all help is appreciated!!
