Perhaps the Dell XPS 15 9550 for $1,500 is an option? It is a 15.6" screen with pretty thin bezels so the actual size similar to that of an average 14" laptop. It is also decently light at 3.9lbs.

It comes with an i7-6700HQ CPU and GTX 960m, 8GB of RAM and a 256GB SATA SSD. The top end model sells for $1,830 and come with 16GB of RAM and a 512GB PCIe (faster than SATA) SSD as well as a higher capacity battery. I think it has a 84Whr battery instead of something like a 59Whr battery.
The only complaint about the laptop is the location of the webcam which is in the lower left corner of the screen. Such is the price for a laptop with very thin bezels.
