Performance matters above all in any computer or device. Buy brand such as Alienware, Asus, MSI, NVidia, AMD, ATi, Intel, as opposed to Dell, HP, Lenovo, and other typical market brands. Those typical market brand will most often have slow performance. Consider a Mercedes and Lamborghini. Both very good cars, but Mercedes will be far slower than a Lamborghini, at the same time with a higher price tag. Same goes for computers. Performance comes at a cost.
