hi i am in the market for a new laptop. I used to have a presario 2100 for about 4 years until it recently broke. I want something that i can play games on (americas army) so it needs to be able to run fast enough and have a good screen, use it for school, a lot of music (ipod), and i want something that has a long battery life. good audio is a plus. cant spend much more than 1500-2000. any suggestions would be greatly appreciated because i have no idea about what i should be looking at
