Pro Does not become hot enough to be uncomfortable
This laptop's WASD keys—the ones that control movement in most games, and as a result the ones you touch the most—get warm during demanding games or longer sessions, hitting 38 °C after half an hour of The Witcher 3 and 36 °C (100 °F) after playing Overwatch for the same amount of time. Those temperatures feel warm to the touch but are not uncomfortable even after long play sessions.
Pro Best price-performance ratio
At $900 the Dell Inspiron 15 700 Gaming comes with a GTX 1060, a 7th generation i7 and with 8GBs of RAM. It provides the best gaming performance out of all laptops at this price range, performing better than even some more expensive models.
In more detail, the GTX 1060 lets you run VR games and can handle even the most graphic-intensive video-games at 1920x1080 without any big problems.
Pro Very easy to upgrade on your own
There's just one screw on the bottom that allows the user to replace/upgrade the HDD, SSD, and RAM. The base model has a 256GB SSD but you can easily add your own to increase the storage size if you wish. It can also support up to 32GB of RAM, and uses a single 8GB stick.
Con Extremely loud fans
Being one of the coolest gaming laptops comes at the price of it being one of the loudest laptops as well. Under heavy load the GPU and chassis fans start working at an extremely high rate which produces noise loud enough to drown dialogues in games unless you use headphones.
