Asus Laptop 15 X509FL
The graphics card, an Nvidia GeForce GTS 250M, is nowadays a garbage. If you expected to play something with this laptop, think again. You will probably not be able to watch at more than 720p in streaming (Netflix, YouTube, etc...) in a fluid way.
More exactly it is the 404 of more than 600 graphic cards.
The amount of RAM is quite short, 4GB were top a few years ago, but today... The operating system itself can eat half that amount.
It is light, so if you are looking for mobility it is a point to count.
