Need help looking for a a laptop under $800

[JP_1013]

Mainly going to use to run visual studio, run emulators such as dolphin, and maybe some video editing and steam gaming. I don't know too much about specs in the sense of what is needed to run certain applications, but these looked like good choices;

The ZenBook and the X555UB both use dual core i5 "u" model CPUs which are rated at 15w max power consumption. Since the ZenBook is a 13.3" laptop that is very light it relies on the Intel HD 5500. The X555UB have a mainstream nVidia 940m GPU. That means the X555UB is better suited for games since it is more powerful than the Intel HD 5500. Both would be competent for video editing.

The Dell Inspiron i7559 is the most powerful of the three laptops. It has a quad core i5-6300HQ CPU and a nVidia GTX 960m which is pretty good for playing games. Most gamers would consider the GTX 960m to be minimum GPU you should get if you want to buy a gaming laptop. The i5-6300HQ would be better for video editing since that could take advantage of all 4 cores in the CPU. Games that can use more than 2 cores would run better with a quad core CPU.

Visual Studio and emulators like Dolphin should run fine on any of those laptops.
