Use
PCPartpicker as a tool.
It will let you know if things are compatible.
The 10900K and the 11900K are the biggest, baddest chips that will go in your motherboard.
Here's how I did it...
Go to PCPartpicker.
At top left choose: Builder
At top right choose: Start New
Then go to "Products"...and click on CPUs
On the left-side navigation, choose Intel, and scroll down and choose: LGA 1200 <---- the socket on your motherboard.
Then, on top right, click on the "price" column, until you have the highest prices at the top.
There you will see the fastest CPUs, that will go into your LGA 1200 socket motherboard.
