He doesn't need anything terribly powerful, just something to play some of the more recent games, and we plan on playing alot of World of Warcraft which isn't extremely demanding =p
Not quit sure of his budget, but I'd bet something under 150 =p
Not quite sure on the game either, like I said w plan on playing World of Warcraft for the present. Maybe some Left 4 Dead. Anything tha can run those two games decently will be fine.
