Which computer would be good for gaming?

ASUS N53SV-XV1 is hands down one of the best laptops you could ever purchase. This laptop has the ability to be upgraded with up to 16gb of memory!!! It's speedy and the graphics are absolutely stunning on this laptop. The keyboard isn't a problem, IF you type like a caveman, then this keyboard will be a problem for you. It has a full number pad and the layout will take you a moment to get use to it, then you will be in love with it as I am. It doesn't get hot and the battery lasts for about 3.5 hours for me, I turn down the brightness some. It has a very sleek look and feel to it, thin and not bulky at all. I would purchase a 17" bag for it as my 16" bag barely covers it. Four gigs of ram is currently good enough to handle a lot of what you will need to do, plus I will be installing Linux on mine.
