Question Upgrade 7600k to 9700k for RTX 2080?

[BenWVU]

I currently have an i5 7600k (4.5 GHz) with an RTX 2080. I’m wondering how much of an improvement an i7 9700k would make.

I occasionally get FPS drops into the 50’s on BFV and the 60’s on Apex Legends. Average FPS is more like 110. My CPU usage is often 100%. This is at 1440p with maximum graphics settings. My monitor is capable of 165 FPS.

I would have to get a new motherboard, so this would be a $600+ upgrade.
