I'm looking to buy the MacBook Pro 13" 2018 with 16GB RAM and 512GB of storage. I want to use it for 4K video editing with Final Cut Pro X and Adobe Premiere. I don't have professional needs. I will be primarily making videos of 5-15 minutes that use one and occasionally two timelines of 4k video. An audio and music track and some extra audio effects on top. A few plugins like lower thirds, titles, labels and plugins and perhaps a couple more plugins that allow image manipulations. The 13" MacBook Pro doesn't have a dedicated GPU so if i get it will I be able to view clips and move through the timeline without there being lag, and will it work fluidly? Whilst I'd prefer to increase the SSD will upgrading the processor to the i7 make any significant difference to performance?
