This is the cheapest I've ever seen a new XPS 15 from Dell. It's the new version with the 7th Gen CPU and GTX 1050, not the old one with the 960M.
1080P Display ( I would get it over the 4k - as you have better battery).
7th gen HQ i7 CPU - a proper quad core and not a watered down i7 like the "U" series i7's.
GTX1050 - One of the most powerful graphics cards on such a small laptop.
For $1840 - one of the best laptop deals I have seen in a while.
Solid deal, although I'd like to make users aware of the fact that this unit doesn't come with a native Ethernet slot
