Fox Stage 3 Upgrage

I’m curious, I know there is a few threads about this, none going too in depth about the difference it has made. I have a 2012 xp 900 with stock fox 2.0’s. They are starting to squeak severely and buck very hard in the whoops. I know this is a common problem with my machine. I am wondering who has gone through with this upgrade and is it worth the $1000.
