Lightroom Desktop: Graphics card

Thank you. Any advice is appreciated. 

@bill_3305731 As pointed out in another post, your info about where the GPU is used is incorrect.  GPU comes into play in more areas than just the Develop module.

Lightroom Classic GPU FAQ

How does Lightroom Classic use the graphics processor?

When configured (Preferences > Performance), Lightroom Classic can use a compatible graphics processor (also called a graphics card, video card, or GPU) to speed up tasks of displaying and adjusting images in the Develop module, the Library module's Grid view, Loupe view, and Filmstrip. Enhance Details is also accelerated by the GPU. Using a compatible GPU can provide significant speed improvements on high-resolution displays, such as 4K and 5K monitors.

Technically true but the use outside of the develop module is trivial, at least on Windows. I've monitored all those non-develop functions and can't get GPU usage above 8%, typically only 2-3% and this just represents the GPU driving the monitor. In fact, just displaying a tab in Chrome or EDGE uses more of the GPU. So if there is any GPU usage outside of Develop, at least on Windows, it is too low to be measured. 

Bill, this was somewhat true in the past but is rapidly changing as Adobe increases functionality that relies on the GPU and, as you noted below, 4k monitors can also have a huge impact as well as increasing megapixels as cameras evolve.

I tested before entering my prior response so my statement is still accurate. I'm using 4K monitors. I agree with you that someday we'll see improvement outside of the develop module but currently it is invisible.

When my powerful Xeon desktop died, I used HP and LG laptops with the integrated GPU. Both machines had different Nvidia MX video cards but Lightroom wouldn't run with either activated so I had the cards turned off. Therefore, just using the internal GPU. 

Was going from a fast Xeon and a medium speed video card to relatively slow i7 machines without video cards noticeable? Yes. But Lightroom was still usable especially on the internal FHD display, calibrated. Too slow to use on the external 4K monitor.  

Everybody has their own definition of usable. As I'm not being paid for my work, I found all functions usable. 

A much bigger issue is that very few laptop monitors, even after calibration, deliver high quality color rendition. More and more all the time but not cheap and they tend to be on heavy gaming systems with less than stunning battery life.
