I know people like MSI laptops, but to me they have a major drawback and that is battery life. You generally get about 2 hours on a full charge when just doing average "daily" tasks. Playing games will likely drain it in less than 1 hour. Therefore, you constantly need to worry about finding an A/C outlet if you carrying it around with you.
Macbooks are pretty good in that they are generally pretty light and have long battery life. They also hold their value very well because... no one else other than Apple sells Macbooks.
I recommend you look into the 15.6" Dell XPS 15 for $1,200. It comes with a qud core i5-6300HQ (MacBooks use dual core i5 / i7 CPUs to the best of my knowledge). It also comes with a nVidia GTX 960m which many "hardcore" laptop gamers consider to be the minimum GPU to get for playing games on a laptop. It comes with an InfinityEdge Display which basically means it has very thin bezels making this 15.6" about the size of an average 14" laptop. That also means it is pretty light at 3.9lbs. The downside is the camera is in the bottom left hand corner of the screen. Battery life when doing average "daily" task work out to 7 - 9 hours depending on which review you read since different review site use different ways to test battery life.

Regarding the reviews, I am not sure if it is the 1080p screen or the more expensive 4k screen version of the laptop (I am at work), it's been a while since I watched them. The 4k screen itself is a $400 option and if the review is for the 4k version it is likely based on there higher end Dell XPS 15 which comes with a 512GB M.2 SSD (PCIe interface) and 84WHr batter (vs. the standard 56WHr battery) which costs $1,830 (excluding the 4k screen).
