The term "Gaming" when added to a laptop normally means "More expensive and more chintzy." For instance, Alienware stuff is more expensive than similar specs on a normal looking laptop.
To be honest, gaming laptops are BS anyway, really. You're not going to get as good of performance as you could in a desktop, and the battery life will be so miserable that it'll be plugged in most of the time anyway. Switchable GPU can help, but it's still not going to be great.
What kind of games is he looking at, other than WoW?
