I switched to a Vega 56 and have an i5-4670K with a 4.0 Ghz overclock.
It seems the GPU is often limited in most cases.
My concern is, can lowering the GPU speed help if my CPU is the main bottleneck?

You won't boost frame rate by merely increasing CPU power, whether through replacement or higher overclocking. Reducing strain on the CPU can be achieved by adjusting graphics settings, but you won't gain additional frames. If your CPU is the limiting factor, it will reach its maximum capacity while the GPU remains underused, producing only the frames the CPU can supply.

Underclocking can significantly lower power usage while sacrificing some performance. The only scenario where this might actually improve how you feel about performance is when you're avoiding thermal throttling, allowing steadier clock speeds even during the most demanding tasks.

InvalidError :
Underclocking might lower power use but at the cost of less performance. The only scenario where this could improve perceived performance is if thermal throttling was occurring, allowing steadier clock speeds despite intense workloads. Oh okay.

No. No no no no no.
Avoid using bottlenecking words in your PC talk.
Except when heat problems cause thermal throttling as InvalidError mentioned, a better video card can never make the CPU slower than before with a weaker card.
Unless cooling is too poor, upgrading to a faster card will never improve performance.
