I use the computer a lot: I'm a student, I like to watch videos/shows/movies, and I do mid level music production.

You should get a Lenovo G510. My brother has one, its great! Or get the one in the first link you put up. I have that one its great for watching movies and everything. You could even run games on it. Hope i helped you.
