I want to use it for gaming like the Sims 4 with expansion packs, mods, CC - games like Texas Chainsaw Massacre and Dead by Daylight and similar games. I also want to use it for personal things - some pictures/music/videos. Ideally I’d like to multitask while playing (Sims, other autonomous games). Which what suit me best do you think?
The 13700k & 14700k would probably be the strongest. Especially, if you want to overclock.
If you never want to overclock, the 13700f & 14700kf are also good options, if you want to save a little $$.
i7 should be plenty for now and years to come.
Even a 12700k would do you right.
