ASUS ZenBook Pro UX501VW Ultrabook
While there are some ultrabooks on the market that are lighter and slimmer, this is a great option if you want better performance and don't need the lightest model possible. This is a pre-built ultrabook so it's not a great choice if you want upgrades and customization, but it includes an Intel i7 processor and 16GB of DDR4 RAM for fantastic performance and program speed. One of the really great features of this model is the inclusion of an NVIDIA GeForce GTX 960M chip with 2GB of GDDR5 video memory which makes this an excellent choice if you want to play some PC games and need better graphics performance. It also has a 512GB hard drive giving you a lot of storage for your files and programs. The 15-inch display on this ultrabook looks great, it's only 0.8 inches high when closed, but it does weighs very nearly five pounds, making it quite heavier than some other options.
