This article focuses on some additional tips for buying a desktop computer that will help streamline your online purchase of a new desktop. Components such as processor, memory, hard drive, optical drive(CD DVD), monitor resolution, wireless card, video card, and desktop audio are all important factors to consider and understand before finalizing your desktop purchase. Bluetooth and TV tuner compatibility are two interesting factors that you may want to consider as well. What you must know is that you will be faced with many more options and decisions to make as you proceed through the customization of a new desktop computer. If you're buying a new desktop computer direct from the manufacturer and customization is allowed then take a minute to read through this article so you know what to expect. If you're buying a new desktop computer from an indirect merchant or if you're purchasing a refurbished desktop then most or all of the customization and options go away and the buying process is much easier(since you're buying the desktop "as is").
