Buildapc

I bought this PC 5 years ago, today it struggles a bit on some games that require a lot of CPU. The graphics card is doing pretty well.

I'd like to update it, starting with the CPU, and switch to AMD, for better compatibility with Linux and notably to be able to encode videos more easily, I often edit long +4K videos.

Do you have any advice? The aim would be not to change my motherboard. And for the new components to last 5 years too? You can also advise me on graphics cards.
