lol thanks for your response Hsv_Man. Actually, I'm looking for a reliable laptop that is very good when it comes to entertainment (playing games, watching HD movies and such) and worth its price. Therefore, since the difference between these two laptops is minor that's why I'm confused regarding which one to buy. Having said that, one of my friends has an earlier model of Qosmio (I don't remember its model exactly but I do remember that it has the same specs as Qosmio X500-123 except for its graphic card) and he's always complaining that even though he paid so much for it, he's always having some technical problems with it and that's why he wants me to get the Vaio.
