I was needing to upgrade from my aging desktop and long since retired HP laptop, so several months ago I purchased a refurbished Dell Precision 7750 laptop. It came with 64GB of RAM (can be doubled if I want,) a 1TB SSD (has 3 more M.2 slots,) and a Nvidia RTX 5000 dedicated graphics card with 16GB. The laptop's a model already a few years old, but I needed to find something that wasn't too expenisive for the things I want to do.
I did recently add a 2TB SSD for data storage and a 2nd 1TB SSD for installing a few versions of Linux. I've made this thing into a windows/linux multiboot system.
The screen it came with was crap, though, running at only 220 nits and 45% ntsc. So a couple weeks ago I upgraded the lcd to 100% DCI-P3/SRGB with 500 nits.
Think I'm finally happy with it.
