I should have sent it back immediately, but I instead went to dell.com and installed the operating system fresh along with the Dell drivers

The cooling system is perfect

Two stars because the system is usable with some tweaking and personal adjustments, but for the expectations set by the hardware specs and price, the experience falls very short of expectations.

Make no mistake, if you have a great wifi system, this laptop will more than be able to take advantage of it, but I often need to work with ethernet, so I killed two birds with one stone by buying a USB 3.0 hub with ethernet.

You could say this laptop is a bona fide "overachiever" as not only is this a great workstation laptop, it's also a VERY capable gaming system

However, I"m not too happy about the 4k screen, it costs a lot extra, but it takes weeks to get one of the 1080p versions, time I didn't have
