Is GPU or CPU more important for Photoshop and Lightroom?

Question

I'm looking to buy a laptop (for a spare) and I'm not ready to spend the amount I did on my first one. The machine will only be used for photo editing. Should I go for the dedicated graphics card or faster CPU? Has there been greater performance differences when using Photoshop with a better/more CPU or GPU?Specifically I'm asking whether a dedicated GPU will offer a substantial jump in the performance of Photoshop and Lightroom over an integrated one, when compared with a faster CPU.**Note:** the question is about *comparing* hardware performance *specifically* of the GPU & CPU when using PS & LR (I've done my own tests & research regarding SSDs, RAM, monitors etc. I'm not looking for help in buying a computer, I'll do that on my own...) *I'm asking the question here because I assume many people using this site have either experienced or researched the topic and I would like to see what the results were*

Answer 1

In Lightroom, the general consensus is that GPU acceleration is beneficial mostly when you have high resolution 4k/5k/retina displays - with a standard display, performance will benefit more from a faster CPU.

I'm not an expert in Photoshop and I don't know what has more impact on Photoshop performance.
