Does a GPU help with photo and video editing?

[Scuzi]

I'm currently working on a repurposed Dell Optiplex 7000 MT. Specs are:
i7-12700
32Gb DDR5 RAM
Intel UHD 770 graphics
2x 2Gb NVME

I use Lightroom Classic & Photoshop for photo editing, and Premiere Elements for video. I also occasionally use Handbrake for encoding.

Firstly, I'm fairly happy with the performance in general, but would adding a GPU to the system make it run smoother? I have recently upgraded to a 40mp camera and the larger files do make it run a little slower, especially when processing higher volumes. Things like AI denoise when I occasionaly use it also take a bit longer.

I normally process video in 1080p but would like to move to 4k, and this is where there is a very noticeable difference in performance. Would a GPU help here?

Secondly, would a GPU that my 260W PSU can support (no additonal power connector required) such as an RTX 3050 be worth it?

2D stuff used to be always a CPU thing, but the newer versions of Adobe definitely do use the GPU a lot more, particularly for the AI features. From what I'm aware of, this is still a case-by-case thing, not every feature does, so it depends on usage.

In so far as, how a 3050 would stack up against the 770, I don't know.

I think a good GPU always helps and the demands of programs will always go up
