All About Graphics Systems
The graphics system of a computer determines how well the computer can function with visual output. Graphics systems are either be integrated into a computer’s motherboard, or they are plugged into the motherboard as a separate graphics card. Graphics systems integrated into the motherboard are quite powerful these days, and sufficient for handling the requirements of most software applications aside from playing games, 3D modeling, and many forms of video editing.
High resolution color images can now be displayed by any form of modern computer graphics on a standard-sized display screen. What the sophisticated graphics cards of today determine is how well a computer can handle the playback of high definition video, as well as the speed and quality at which 3D scenes can be rendered. Another key feature of a separate graphics cards is that most of them now allow more than one display screen to be connected to a computer and some others also permit video recording.
When it comes to final performance, the more RAM and the faster and more sophisticated the processor available on a graphics card the better. Having said this, good graphics cards can cost quite a bit.
Graphics cards connect to what is known as either a “PCI Express” or an “AGP” slot on a computers motherboard. PCI Express is the more powerful and modern standard. The best graphics cards require the use of two PCI Express slots. A PC being upgraded from onboard graphics sometimes also requires an upgraded power supply for it to continue to run in a proper manner.
