Hello. I am in the market to buy an IMac 2019. Aside from the normal office work, I will be doing the following 1. Photography for my business and freelance work. Shots are on a Panasonic S1R. 2. Video editing for free lance and business - less extensive. S1R 8bit 4K 24fps. Includes Motion, DVR, APP, FCPX 3. Various graphic design work. 4. Bunch of tabs open 5. Logic Pro X I am upgrading the ram and drive to 512. My question is should I upgrade from the 9600k to the 9900k or the 580x to the 48.
