If you are looking to purchase a PC graphics card for your computer, then there are three things you will need to consider prior to picking one – speed, performance and card type. A graphics card, sometimes referred to as an adapter or accelerator, is a video card that goes inside your computer to control the output to the monitor.
There are two levels of graphics cards to handle the types of graphics you need: 2D graphics cards which are designed for business applications and 3D graphics cards which are more suited to gaming and video playback.
When it comes to performance adding a high speed graphics card to your machine will greatly improve the way your computer runs applications, because you will be replacing the standard on-board graphics processor that came with the computer when you purchased it, with a high performance 3D accelerator card.
There a number of different graphics card manufactures but when it comes to chipsets there are actually only two companies that produce the ones you find on graphics cards: ATI and NVIDIA. Known as graphics processing units or GPU’s, they are the brain center behind the card.
