Well, it depends upon the price for which u get it like at the Microcenter you can get 10900k for like 200 bucks.

I disagree, $200 still not worth for a 10th gen processor whether if it is the i9 10900K, instead you should get an i5 12400/F or even an i5 12600K if youโ€™re able to squeeze more budget, even though it was in 2021.
