Meh at 4k you can get away with even older cpu than 10700k.

Anything really, however maybe think about switching to 1440p monitor. A good monitor will last you for longer than any gpu.

I switched from intel to amd, i have no regrets. As a gamer i feel like amd just offers a better package than intel especially now when ddr5 prices are acceptable. Lower power draw, easier to cool, platform that will allow for more upgrades than intel, x3d chips.

Every gen, im inclined to support multibillion dollar corporation.

But in full honesty just recently i made a first real update and went from 4790k to ryzen 7600. So from 2015 to 2023 i was managing with good old 4790k.
