I am looking to by a la and to ptop. I intend using it to watch videos DVD/Bluray play games grand strategic such as Hearts of Iron III, first person such as Call of Duty and possible flight sims. Will probably send £2000-2500 and weight is not an issue. I have been looking at Acer 8943g, Alienware M17X and Asus G73H-A2. Any suggestions?
