PC for the Creativ Cloud

Hello, I'm about to build a PC for programs in the Creativ cloud. First I want to say that my english isn't the best, so I'm sorry for some mistakes! My Budget is 2000 Euro (approximately 2250 Dollar). I don't know if I shold Buy a AMD processor or a Intel processor. I'm going to work with Premiere Pro and 4K files, Photoshop/Lightroom and files from my Sony Alpha 7 III (One file is 24mp big). Maybe I will work sometimes with After Effects but this program is not important for me! Is the Graphics Card necessarie for this programms or is the processor more important? Should I buy a RTX 2080 or a Quadro Graphics Card? Or are the Graphic Cards of AMD better? I hope you can help me!
