There are other things you can do. You just have to look. I have a paper route. You could mow peoples lawns, rake leaves, work on a farm, there are a lot of things you can do. You dont have to be 16 to get a job.
EDIT: So wait, you dont have a video card but you are asking if you should get one? [sarcasim] No you shouldnt get one, get memory instead [/sarcasim]
