Keep in mind HP doesn't "make" a single laptop, neither does Dell, Lenovo or most of the major brands you'd know. These are all build by ODM's and it can be funny to watch people's reaction when they find out that the brand they love is made in the same factory as the brand they hate . The thing with "gaming" laptops or better known oin the industry as "boutique" brands is that they also are made by someone else.....and if ya cut out the middle man, you can oft cut ya price by a third.
