Add a Sound Card or Video Card
Video cards and sound cards fit neatly into open PCI slots in your desktop PC. Though many motherboards include onboard sound, and onboard video or a basic video card, upgrading can give you better and faster performance. Start out with the best video card and sound card possible when building your desktop PC from scratch.
Improve your desktop PC's video performance
Put a TV in your desktop PC or get lightning-fast video performance for your 3D games and movies with a new video card. Video cards go by many names, including graphics controllers, graphics accelerators, graphics adapters, graphics cards, graphics processing units (GPU), video boards, video accelerators, and video adapters. Whatever you decide to call them, video cards handle all the 2D and 3D calculations and rendering on your desktop PC.
The most important thing about buying a video card is finding the right one to fit the slot on your motherboard. Most high-end graphics cards require a PCI Express slot. While some card makers still make AGP versions of their cards, they’re relatively difficult to find.
You'll want your video card to have the fastest speeds possible for gaming. Look for an ATI Radeon or an NVIDIA GeForce; the higher the number the faster the card. For multimedia machines, get an ATI or NVIDIA card with VGA and/or DVI outputs.
Look for a video card that has a TV tuner if you want to watch television on your computer. Also, if you want to use two monitors with your computer, look for a video card that supports dual monitors.
Step up your desktop PC's sound system
The latest motherboards with integrated sound sport six-channel digital sound chips that support digital 5.1 sound reproduction. They are more than adequate for casual gaming and MP3 playback. If you want to produce music on your desktop PC, get a standalone sound card with plenty of connectivity and a high wavetable.
Sound cards work as a synthesizer, generating sounds, and can include a Musical Instrument Digital Interface or MIDI interface to connect to electronic MIDI instruments. They also work as an analog-to-digital converter used, for example, in recording sound from a microphone, and as a digital-to-analog converter, reproducing sound for a speaker.
