You'll absolutely be shocked by how much faster it will be. I went from 9900k to 14700k and I was.
I was going to wait but didn't think it was worth dealing with new teething issues of the 15th gen chips and accompanying boards. Also didnt want to be forced to a new a new OS. Very happy with Windows 10.
I use premiere pro, photos hope etc and coming from a 9900k I was really disappointed seeing similar videos about lag, and was thinking I just made a bad decision, especially since I wanted to keep Windows 10.. .
Anyway, a few weeks into using my 14th gen build I'm wondering why I was even stressing at all... absolutely snappy and responsive.
You could meet in the middle and get 6400 titanium c32
