HP pavillion DV9010tx also known as "the game changer"is really a modified one, besides the OS the graphic is perfect with the size and resolution. didn't know why the RAM is accurate yet I didn't need any external graphic card to play any large games. I'm also really satisfied with the price. All HP laptops or computers are different comparing their model no. To their system and this Model is yet my favorite one. No other companies like Dell or lenovo make such performance.
