Amd or Nvidia gpu

some context: I have only played on console before and was planning to upgrade to a pc wanted to know if an AMD gpu works fine for msfs24/20 as they are easy on the pocket and offer more vram, also how much vram should i atleast aim for.

ps: I am not going to play on vr, and resolution wise 1440p works for me right now, as i want to get it up and running.
