4K gaming as you read http://www.cnet.com/news/hands-on-with-nvidias-new-titan-x-graphics-cards/ looks to take a trio of Titan X's to get 47 FPS on 4K displays. No laptop made has enough GPU power to do this.
Why 4K? It's not like you can game at 4K yet.
Hey, I'm a student/gamer looking for a new laptop. As a result I need one that's portable but also has the specs for some basic gaming..nothing too demanding. But I also need one that's portable and preferably looks good. I was looking at the new dell xps 15 (the "4k" model).. I heard some bad things about the older versions such as wifi and heat problems and I was wondering if these have been fixed? Also any other similar suggestions would be appreciated!
