You should only buy a computer to meet your needs. Ask yourself what you will be using your computer for? If it's for simple email tasks or surfing the web – you don't need a big expensive machine with all the costy extras. If you're into video gaming or editing large video/graphic files you may need a more expensive fast computer with high-end quality graphics. In other words, choose the computer or laptop that will take care of your needs and tasks. Save your money by buying only what you need.
