Personally I dont think bottlenecking a GPU exists, what people are saying is "if you had a better processor, you would get better performance out of the card" but games dont 100% rely on game graphics card so you arent actually getting better performance out of the card itself but getting more performance out of the better componet. Besides, you wouldnt have worry about "bottlenecking" anyway.

I am not really sure how people base their statement on how to classify if you are running a "bottleneck". Maybe if you CPU performs worse than the best cpu available with the same videocard, maybe then thats bottlenecking?

Easiest way is to run Aquamark3

At the end you will have a cpu and gpu score. It'll be obvious which one is the bottleneck.

Run identical GPUs on CPUs with different speeds. It’s helpful to find
a system BIOS that allows you to adjust (i.e., down-clock) the CPU speed,
because that lets you test with just one system. If the frame rate varies
proportionally depending on the CPU speed, your application is CPU-
limited.

Reduce your GPU's core clock. You can use publicly available utilities
such as Coolbits to do this. If a slower core clock
proportionally reduces performance, then your application is limited by the
vertex shader, rasterization, or the fragment shader (that is, shader-limited).

Reduce your GPU's memory clock. You can use publicly available
utilities such as Coolbits to do this. If the slower memory
clock affects performance, your application is limited by texture or frame
buffer bandwidth (GPU bandwidth-limited).


Generally, changing CPU speed, GPU core clock, and GPU memory clock are
easy ways to quickly determine CPU bottlenecks versus GPU bottlenecks. If
underclocking the CPU by n percent reduces performance by n percent, then
the application is CPU-limited. If under-locking the GPU’s core and memory
Was that helpful? /\\

The closer they are the better, as long as there isn't a huge gap between them its nothing to worry about.

My cpu and gpu both get 11.5k
