Looking to upgrade my current POS laptop to something that can run WoW on something more than potato quality. One of my friends has a laptop for sale, and I am trying to figure out if it is a good deal. The laptop is 3 years old, but has seen minimal use due to have more powerful machines. This is the computer in question: ASUS G74SX-A1 17.3-Inch Gaming Laptop - Republic of Gamers
He is asking 500$ for it. Is this a good deal?
