Looking to upgrade/improve build

So I built my pc on a budget a couple years ago and it has done what I have wanted it to, but wanting to upgrade my build to get better performance. So I am wanting advice on what some of you think would be a good next step, and if there is anything I should change/add/do. I am currently on the west coast of the USA, budget of $500USD or a little more if it makes more sense. But can wait on getting parts if need be, I am not in any real rush.

My current build is MSI MPG B550 gaming plus motherboard, AMD Ryzen 5 4600G SPU, AMD Radeon RX 5700 GPU, EVGA BQ 700W Bronze PSU, 16gb DDR4 RAM set and a 32GB DDR4 RAM set, SSD 1TB and 4TB hard drive with 3 intake and 2 exhaust fans. I have a dual monitor set up, main monitor is 32.5" MSI Optix G32 Series curved gaming monitor, and second monitor is ACER 24". Running on Windows 10.
I use my PC mainly for gaming and watching yt, anime, etc. Most the time while gaming. But I am also wanting to get into video/streaming shortly. I have done some searching on my own already and what I am thinking of getting is the AMD Ryzen 9 5950x and a new heat sync, or I have been playing with the idea of liquid cooling but not sure how well that idea is for me, so probably fans better idea to stick with for now.

So what say you random Redditors? Got any good words of wisdom/advice for this novice PC user? And if I left out any information that is needed, feel free to ask, I will get back to you as soon as I can. And thank you in advance for any and all advice you give
