CPU bottlenecking gtx 1080?

[Tdozer96]

Hey all,
I’m looking to upgrade my CPU ( intel core i5 6600k OC’ed to 4.5ghz) . Was playing the new cod and noticed it was being used to the max. It’s already overclocked to 4.5ghz. I know it’s the cpu because when I close out everything else, especially discord, I get a noticeable improvement in FPS. I’m not sure what I should get between the i5 9600k or ryzen 5 3600. But obviously it’ll suck switching to ryzen because I’ll have to upgrade additional stuff then. I wouldn’t mind getting something more than the i5 9600k but would it be necessary and would I notice the difference? I’m looking to keep it all under 300$. But if I stay under that price would I still be bottle necking my gpu?
My current specs are 

•GTX 1080 fe (OC’ed with aftermarket cooler)

•INTEL CORE i5 6600k ( OC’ed to 4.5ghz)
•16gb ddr4 2400

THANKS IN ADVANCE!!

well you wont be able to keep it under 300$ if you upgrade to a 9600k because you would need a new motherboard as well. Your best option if you want to keep it under 300$ would be to find an i7 7700k.

My motherboard already fits the lga 1151 socket type?

Socket type isn't the only contributor to compatibility, you need to look at chipset as well
