DeadlyDays,
In some ways I agree with you. As a recent buyer of a laptop, who never intends to plug it into an external monitor, I don't need to spend money on a more expensive graphics solution than that necessary to run the laptop display at acceptable levels for me. I bought a cyberpower that had a 1080 ips display. I went with the 970m graphics option, due to the extreme cost and lack of value in going with the 980m(I might on my own swap in a 980m, but it's still not a real powerful graphics setup). I'm not going to need more muscle than that needed to run 1080 well.
Here's where I disagree with you. A single 980 won't run 4k effectively, only 1440, and frankly 1440 is rapidly becoming obsolescent. I've never seen a laptop with a 1440 display, although it is intriguing. Until there's a laptop that has 980tis in sli, there's no need to buy a laptop with a display of more than 1080, if you plan on gaming, due to the lack of graphics processing muscle. Unless you run your display at lower resolutions........
