Recommendations for Windows computer around $1,500? [was: I'm flummoxed!]

[Rich2222]

The recent purchase of a Nikon D850 producing 92megapixel files, and a sudden passion for astrophotography have combined to stress my 10-year-old Dell Precision T3500 Workstation to the breaking point. In addition, it doesn't seem to be able to handle the updates that Adobe has been sending my way recently. I've been frustrated by the sheer volume of available systems out there! I'd really appreciate any suggestions on a Windows computer. My budget is limited to around $1500.00.

I've pretty much settled on a Dell Precision 3660. The one thing I'd like to ascertain is the compatibility of Photoshop with the Intel UHD770 graphics chip that it's got. 

I'd hate to buy it only to  keep getting the warnings that I'm getting with Methuselah, as I've come to refer to my T3500,

I would avoid integrated graphics and go for a PC with a dedicated GPU. See system requirements here:

Incidentally, I thought the Nikon D850 had a 45.4Mpixel sensor
