Yea well I would have to buy a new mobo cause the warrenty ran out(of course:) but I am going to wait a while cause I have no money and I have no source of it either at all. plus my dad lost his job.
My advice for you to wait.
4GB RAM is enough for you now.
Get some job. And my wish for your dad too, so that he can get back some job. Never loose heart.
