CPU or GPU?

I’m planning to work in Visual Components designing warehouses. These are very resource-intensive simulations. Could you advise what’s more important for faster performance, CPU or GPU? Also, what computer specs would you recommend to avoid low FPS issues?

According to my understanding, the simulation of visual components is divided into two parts: data simulation mainly relies on single-core processing by the CPU, while model rendering requires GPU processing.

CPU with a high single-core performance is the main performance contributor from hardware side.
