I faced similar problem of replacing my windoze laptop this spring. I photograph a 5-day festival every year and the post processing burden was not going to be a happy event with my old computer. After thorough consideration (including switching to Apple) I bought an Asus ProArt Studiobook 16:
Mine is the version with 32 MBytes and RTX4070 graphics accelerator.
This has been a great upgrade. Lightroom and Photoshop now work with no lag. Enhance, which took tens of minutes on the old machine, is now near instantaneous. It has a calibrated OLED screen with near 100% Adobe color and low delta-E.
It includes an active stylus which works both on the (touch) screen and on the track pad, so I no longer need a Wacom pad which took valuable desk space. The pen has no discernable latency and is amazing.
I use Topaz Photo AI on almost every photo now (I usually shoot in low, uneven light) and it takes about 10s to render and output a full-size tiff (Z8/9 sized).
It is supposedly built to near military standards.
Downside is: Performance degrades when unplugged from power; The power BRICK is enormous. Good news is that it comes with a backpack.
There is a new version out called the Asus P16. There are not many reviews of it yet. It uses an AMD processor instead of an Intel i9. Same graphics card available. In early reviews it performs better than the old version when unplugged, but surprisingly is behind the previous version when plugged in.
The transfer from my old computer was easy. I use the internal ssd during processing, external storage for intermediate/long-term storage and backup, and also Backblaze, and have no problems.
I am very happy with this.
Hope this helps.
