I am replacing my 2500k with a new 9th gen build. Going from 4 cores to 8 cores should make a difference for me since my system is 7 years old. I game at 1080P and edit youtube videos. I already have a Maximus XI Hero and RTX 2070 ready to go. I can't decide between 9700k or 9900k. I tend to keep my computers for over 5 years without upgrading. The 9900k is $579 but out of stock, the 9700k is $409/419 depending on where you look.
