"On a bit budget" and linking the 12th generation 12600k, come on dude. Just because u have 12900k, everything below that isn't considered budget.
Then you talk about a motherboard, just because u literally have that exact motherboard, then u talk about the 980 pro, just cause u literally have a 980 pro, sorry but i found those posts so cringe, dont get me wrong. It's amazing that people help eachother, but always recommending specific items cuz u have them is so cringe.
If you have them and like them and wanna share that info with others, fair enough, but that doesn't turn everything below those items into budget. Just because you drive a $500k car, doesn't mean that someone drives a budget one cause he only payed $400k, i think you get the point. If you not plan on playing everything on ultra in 4k you don't even need to worry about being above the 10th generation to make it playable. You don't need more than 6 cores on a cpu for gaming today, a i9 performs the same as a i5 in games, the i9 will just be much faster when it comes to rendering and editing which doesn't show within games. You can also see that in the link you sent yourself, barely a difference between the top 2 cpu and one is i9 and the other one is i5
