What kind of laptop would you suggest for the Sims?

I need a laptop that can hold all the Sims2 expansions and the ones that are coming and My friends laptop is so fast it only takes 5 secs to load the game. 10 sec to get to the neighborhood. 20 sec to go to lotys and creat a family. Mine takes 3 times as much in minutes. One time it took a HOUR. I have an hp. my friend has a tOBISHA. I dont know how she custimized hers but her graphics are weird!!
