Good gaming laptop under $350?

Ok, I have an Xbox 360, and so does my best friend. (he is spoiled out of his mind, has 46 Xbox 360 games, we counted) anyway, he has this $1,000 laptop that he uses for gaming, and it sounds fun, I have played the games. Anyway, what is a good gaming laptop under $350 that can support 1. Minecraft 2. Garys Mod 3. GTA Sanadras. I would like to download mods and what not to them. I am on a budget.
