Gnits, I'm really sorry to hear that. I don't know how Dell holds up service-wise in Europe. There are probably better choices over there. I live about 40 miles from Dell HQ in Austin, but I guess that means less and less these days as parts are sourced from all over the world and the Dell computers have factories and build shops all over the world. All Dell computers used to be built in Texas, but now they have spread out their manufacturing and assembly processes worldwide. The Texas plant now handles only servers and other industry-grade computers.
But your experience with Dell and that amazing XPS-15 (which is the very best laptop for travel productivity in my opinion) is amazing and very surprising. What graphics card was it? Dell uses Nivida, which are the best there is (in my opinion), so anyone who says those GPUs don't work well with LR and PS is way off. Incredible that a Dell tech would say something so crazy.
Sorry, that happened and I'm very surprised they didn't immediately mail you a new laptop. Sounds like you had a bad GPU, but who knows. Something was not right, which can happen with any computer maker.
Your experience was probably a rare occurrence, but Dell is a huge company and one of the biggest, if not the biggest, computer makers and I guess these things happen. In fact, I had a new XPS-15 go down after one week 32 months ago with a bad Wi-Fi antenna, which is a tiny little wire module on the motherboard. Dell sent a tech out the next day and found the fault. They mailed me a new machine the day after that with a bigger M.2 SSD as a way of saying I'm sorry. That was a hassle because I had to reload everything, but they were good on the reaction time.
I'm on that 32-month-old Dell XPS-15 right now and it is out of warranty. It was 2,800 bucks 32 months ago during the Pandemic and it was absolutely as fully loaded as you could get at the time. It is still very snappy with LR, but I'm not going maybe another 6 months with this machine. 3 years on a laptop is the max for me. Too many improvements to stay away too long....
