If like me MSFS is your main aim and not productivity, go for a 7800x3D and a 4090. Heck, even my 5800x3D with my Asus 4090 still knocks my socks off with a G2, or my Pico 4 for that matter. If the Pimax Crystal pans out (or something better actually comes along) you may want to buy one and they will both definitely need at least a 4090.
