Which of these laptops is better at gaming?

Personally Alienware makes some of the iest computers out there and they last like an energizer bunny if money was not an issue i would go with the area 51 over the asus all day with a msrp of $1799 for the area 51 and an msrp of $1499 for the asus i would still go with the alienware. Just do your self a favor keep your software safe (you never know). and for some reason i have to get the asus software from asus them self and dell computers send software with all there computers. Every prefab computers ive ever owned was a dell there awesome to me and best of all if you customize your alienware laptop you can get it exactly how you want it to look run how fast you want it ect.. just go to dell.com go to for home tab let it fall down then click alienware and customize the laptop of your dreams just watch what you get i made one over $6000 it would be one sick laptop but not realistic... Well happy shopping
