You will notice it, only in the form of how much FPS you get, when the GPU is the bottleneck. You can try playing with lowered graphics settings, in whatever game you are playing, if the FPS isn't good enough, for an enjoyable experience. You are never going to eliminate bottlenecks, something will always be one somewhere. It's just a matter of how impactful they are. With a 3700x, at 1080p, I would say you are good till at least a 2080 super. If you jump up to 1440p, or 4k, I would say a 2080ti, 3070, or 3080.
