Difference in performance between a low range and mid-range graphics card?

I’m in the process of migrating from my macbook pro to a windows pc build since I’m over using parallels, and deciding whether I should get something like the Nvidia RTX5060 TI for the sake of increased chart performance. Otherwise I will run it with the integrated graphics that comes with the intel i9 CPU.

I use 48 charts that have 2 SMA’s and a few watermarks, bar timer etc so there’s a lot going on all at the same time.

I would imagine a dedicated graphics card would take off a bit of the load but I’m curious at which point will there be absolutely no difference in performance and latency ie a 5070TI compared to a 5060TI.
