I am considering buying the alienware m15x (dell.com/us/p/alienware-m15x/pd?refid=alienware-m15x&s=dhs), but it seems like a lot of people that I have seen talking about buying it have upgraded their's with better hardware than the stock $1199 price. I am looking to spend right around $1199, but hopefully not much more. I was wondering if anybody could take a look at it and tell me if I could buy the m15x stock, and still have it run wow amazingly, or what upgrades wound be considered as something "I have to have" with it. Other options are the Toshiba x505 (toshibadirect.com/td/b2c/laptop-model.jsp?family=Qosmio&model=X505) , and the asus g73jh (usa.asus.com/product.aspx?P_ID=8je5Ot4HBnKOdT81).
tldr: I want to buy an alienware m15x but not sure what I should, if anything, upgrade on it.
