Never buy anything you can't afford, especially on credit. I would go further and say "just because you can afford to buy something, doesn't mean you should".
Don't buy anything now. Start saving your money until you have the excess funds needed to facilitate your upgrade and do it then. At that time you will be bargaining from a position of power, i.e. you have an existing system and you have free cash to spend on an upgrade if the right deal comes along.
