I'd avoid Alienware. Their stuff has always been overprices and since the Dell buyout it's only gotten worse. In fact, gaming laptops are pretty ridiculous all around. In most cases you could get a high-spec gaming desktop AND a smaller, lighter, more portable laptop for less than the gaming laptop would cost.
