I want to buy a laptop but at same time idk?

Okay, i have a pretty fair amount of money saved up, not much, but about $400?? I have a job, so im steadily putting more money into that amount, im thinking of buying a laptop and paying a certain amount of money monthly. But also idk if i want to buy one. I want it to play a new game that is coming out : Star Wars The Old Republic. I might play WoW and etc etc. any thoughts or laptop suggestions? more then likely i will end up just saving the money.
