What is a gaming computer and where can I buy one?

You are going to want a Alienware System them. They are made for gaming and can not be beat on Graphics, Ram, Hard Drive , or Processing Speed. You can find them many places, but My favorite is Microcenter. They have a Dozen stores around the country and you can also purchase it online. They have a huge clearance center too! They also do in store pick up in 18 Minutes or less. http://www.microcenter.com/ is the main page. You might be internested in the Alienware Aurora , Its Steep but Loaded for gaming.
