So, my best friend has been in the Air Force for about 3 months now, and he's finished his basic training and is now stationed somewhere in Mississippi. He wants to get himself a custom built PC so that he can play the games that him and I used to play together on, like Splinter cell, Assassin's Creed, WoW, that stuff. And with Assassin's Creed 3 PC release right around the corner, he wants to get it soon so we can have some fun with that game when he gets spare time. His paycheck is somewhere around 400-600 a month and his next paycheck is due this Thursday, so does anyone have any suggestions to some fairly cheap parts that are decent enough to give him a good playing quality?
