Hi, planning to change a new laptop since my previous one died on me

Anyways here are my requirements.

1. Budget friendly 1.5k and below
2. For everyday use (movies, youtube, documents)
3. casual gaming (dota 2, etc.)
4. engineering softwares (HYSYS, AutoCAD)

I'm just a normal guy with day to day usage only. Only thing Im heavy on are movies.

Appreciate it if anyone could suggest me some affordable ones.

Been looking through:

ASUS X550DP ; Lenovo G40-45 ; HP 15-G201AX

Or are there better choices for me out there?

Thank you thank you thank you thank you thank you !

OK Thanks !

Will open up my options for this model as well..

Wow ... dint know autocad need that much of RAM @_@
