I just built my new PC (three days ago) with a i5 14600k and I am very happy with it. I was thinking between 14600k and 14600kf, but I went with a K because of the integrated graphics card. Which was a blessing because my new graphics card was acting out (as I thought at the time) and it allowed me to troubleshoot the system. If I went with a KF that has no integrated graphics card, I would have been in a major pickle. All in all it was not the graphics card that was the problem, but somehow my windows installation was corrupted and it got fixed with another installation.
To be fair there were a few things that influenced my decision:
Basically this was enough for my needs. I always look at my needs first and then at price vs performance. As I said, my needs have changed in the last few years so I decided not to go with the absolute high end PC like I used to do (back in the day). I hope this helps.
