If you pair an underpowered CPU with a relatively highend gpu your gpu can't perform to its full potential and vice versa. But like @Slotter said it depends on what you are doing. Also there is no system with the perfect GPU and CPU combo, meaning no bottlenecking otherwise there would be infinite power.
It hinges largely on your specific tasks with the machine, but maintaining a fair balance is usually wise. For instance, if you're mainly writing code or handling CPU-intensive jobs, a powerful 7000-series processor like the 3950X paired with a budget GPU for display purposes works well. The CPU can perform at its peak, while the GPU focuses on rendering images. Conversely, when gaming demands heavy GPU usage and moderate CPU involvement, that setup won't be optimal. You'd likely perform better with a mid-range CPU such as the 3600 and a more capable GPU like the 2070 Super, allowing the graphics to handle complex scenes efficiently and the CPU to stay responsive. Ultimately, finding the right mix depends on your workload.
You can mix and match whatever suits you, but some setups won't work as well. If you invest in the best GPU available but have a weak CPU, it will struggle to keep up, making your investment feel wasted. It's smarter to allocate more to the CPU and choose a better GPU so both components perform in harmony.
