I'm looking to purchase a secondary computer for working away from the office. Most of my work is in Adobe Premiere Pro, Photoshop, After Effects, etc. I work on mostly short-to-midlength videos but sometimes have to do heavy color work, resizing, time remapping, etc (esp with drone footage). Currently I'm mostly working in 1080p but I may be working with more 4K down the road so good to be prepared for that. I am looking at getting a 15" MacBook Pro but trying to determine whether the $2,399 model would be sufficient for my needs or if I need the $2,799 one. We're a nonprofit so would obviously love to save $ if possible but not compromise being able to work efficiently... Thanks much!
