the way I see it you have 3 choices
- stay below 1.5K and just have a nice 2022 mid range pc from scratch on AM5 platform or like a 12600k with the GPU being a 3060/4060. its going to be fluid and snappy however, will take its time while rendering anything large
- be about 2K and squeeze in a nice little 3080(12gb)/3080ti/4070(maybe even ti) if you will really benefit from GPU acceleration in your software and have a nice little bonus of being able to considerably crank up graphics settings in single player for the next 2-4 years even though you never mentioned those games once
- go balls deep 2.2-2.5K and have a crazy rendering rig that you can game with on the side
in which ever case you are going to need this https://www.dealabs.com/groupe/cartes-graphiques because high end GPU prices are still bonkers
i just really dont know how well recent AMD card accelerate editing software
the part I am still trying to figure out is how serious you are about the whole editing thing because it seems to me you are on a 1080p 8bit screen whereas ideally you'd have a 4K monitor with 99% DCI-P3/Adobe RGB coverage and I dont think a 240hz panel older than 2021 has even half decent gamma coverage
either way I would suggest you get 32Gb of RAM, 12Gb of VRAM and ideally at least 8 Cores, these wont do you any good in tf2 but if youre serious about your video and photo editing i would look at R7 7700/i5 13600k at the very least
figure out which of the 3 choices suits you best and ask the german guy for parts
