I have an Alienware M17x r4, fully loaded; 16gb RAM, 500gb hard drive (kinda want to add an SSD), i7 3610m, 660m GT. I have an Asus ZenBook Prime UX31A-AB71 I'm looking to sell just because it doesn't meet my standards. I'm looking to get a rMBP and replace it with my ZenBook, Alienware, or both. I game sometimes, do some work in PhotoShop, and use it for class. Suggestions?
