If I upgrade my GPU, will I get the same FPS because my CPU already bottlenecks my current GPU?

My current CPU is a AMD Phenom II X6 1100t 6 core.
My current GPU is a AMD RX 480 8gb

My current CPU bottlenecks my GPU. (Only by a little)

Currently, I get around 100 FPS in my favorite games on max settings on 1080p.

However, if I upgrade my GPU RX 480 8GB to a high end card like the GTX 1080ti, will I get the SAME amount of FPS as my old RX 480 using the same CPU? (Because my CPU already bottlenecks the RX480)

To be clearer:
1. AMD 1100t + RX480 8GB = 100FPS
2. AMD 1100t + GTX1080ti = 100FPS ???

Is this how the FPS works when bottlenecked by the same CPU?

i'd say not anything major to warrent the cost.

It would be better cost and performance to upgrade the rest of computer so current GPU isnt bottle necked and you get full performance out of it.

TBH i'd focus on the main components for now as 10 series card may lower in cost after the 11 (or w/e they will be called) series come out later.

I'll make it easy.

1100t + Rx480 = 100fps = $0
1100t + gtx1080ti = 100fps = $1200
I5-8400 + Rx480 = 150fps = $400

A bottleneck is a component that slows down the flow of info. A cpu can be a bottleneck if the possible flow of info is squashed there. So if the cpu is only capable of decoding the game engine and providing 100 frames per second to the gpu to paint its picture, changing the gpu will do nothing more than put a higher demand on a capped out cpu. You still get 100fps. The only real fix is replace the cpu with one that's stronger and can provide greater amounts of frames under gpu demand.

An Rx480 is just fine for most 1080p gaming, only a few% behind its newer revamp, the Rx580.

The gpu isn't the issue.
