This version is very little different from my 2012 XPS 8500. I upgraded mine from 8 GB to 16 GB RAM, and it has an AMD video card instead of nVidia, but it's basically the same machine. What can I say about it?
The only mechanical problem I've had with it is the power supply failed once, about 2 years ago. The power supply in the Sony Viao tower I had before the Dell also suffered a power supply failure.
Other than that, and replacing the DVD drive with a BD R/W drive, seems pretty much apples vs. apples. And I paid $1600 for mine (with only 8 GB RAM). In May, 2012.
At less than $1000? A really good deal.
FWIW, Win10 runs great on my XPS 8500. AMD's Win10 driver is still a bit glitchy, but Win10 recovers great, whereas Win7 would have crashed. I'd check for comments as to the nVidia's Win10 driver, but I'd pick one up if my current PC needed replacement.
