Should I get an Alienware m11x?

Im a serious gamer who already ones a desktop that can play any pc games on the market at max settings with ease. I will also have all the current generation video game consoles once my 3ds come in the mail. But my main use for an alienware m11x would be for portability and power so i could play simple things like WoW, Rift, League of Legends, Elder Scrolls IV and Skyrim later this year. I would be taking it places for LAN parties of LoL and Civ V so portability is a must. And i dont mind not being able to play games like Crysis on high settings but more like medium to low settings if at all.Once again i emphasize that i dont care weather its a powerhouse but rather a modest laptop that will suit my specific needs.
