Im serious, buy a MX14 or 17. And buy an Alienware if you want a gaming laptop. It costs more but trust me it's worth it, cause the cooling on many other laptop manifacturers simply isn't enough for gaming usage. Quite litterally burned myself at this the last time I bought mine, it got so hot that now, 3 months after the last time i used it for gaming, I STILL DONT HAVE FINGERPRINTS ON MY PINKIE FINGER! Seriously, no fingerprint! My pinkie finger is scarred for life!
Too expensive? Yes I agree. And there's no knowing whether GW2 will be out in 3 months or 2 years. Nor is there any knowing if you're new laptop will actually handle GW2 well, because it's not always as simple as a yes or no answer. Mine handles some games excellently and others games not at all, even though you'd think it would handle the games i doesnt, and not the games it does. Gaming laptops are moody creatures!
In general I'd say buy two computers in stead of one, 1 stationary computer for gaming. And 1 laptop for beeing on the road. The laptop will likely work just as well for normal school related tasks, and the stationary computer will be significantly better then a gaming laptop even at a low price.
But if you buy one, BUY QUALITY!
