Seems like a decent laptop to me. I haven't been in the market for a laptop since I was in college so I can't say how it is in terms of price compared to other laptops but it should perform pretty well in games.
The 1000 series GPUs are so power efficient that Nvidia doesn't even make mobile GPUs anymore. They just put in the full desktop version of the GPU and run the clock at a slightly lower speed to reduce the power requirement and heat output. That is a mobile CPU from Intel but it shouldn't hold you back too much. All Intel i5 or higher CPUs from the last 5 years or so still do pretty well in games.
The x50 GPUs from Nvidia certainly aren't near the top of the power charts but they do pretty well for high to medium settings in most games at 1080p. The 1050 Ti is a little better than the GTX 960
yourbeliefs had in his previous build. That laptop is not going to be a gaming powerhouse the way a desktop could be but it should do pretty well for gaming as long as you don't care about max settings at 60 FPS in the most demanding games.
