AMD Ryzen 7 5800X?

I have an RTX 3060 12gb, with a Ryzen 5 5600G, and 16gb of RAM.
I play everything in 1080p at 60fps, even with my 1440p 165hz monitor, and I keep getting major stutters and FPS drops, when I play War Thunder om Low-Medium settings. When I tried the Battlefield 6 Beta a few months ago, it ran horribly, even on the LOWEST settings.

I am considering getting an AMD Ryzen 7 5800X to increase my PCs capabilities, and eventually getting more RAM (hopefully).

Anyone have any suggestions or corrections?
