Dell Inspiron 15 5502
The graphics card, an Nvidia GeForce GT 330M, 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 476 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.
Oh and be aware, if you're still using jack/mp3 connector, this model DOES NOT have it.
