Advanced Graphics Port. A dedicated high-speed interface between PC memory and a graphics card and monitor. Before AGP existed, graphics cards were fitted into standard PCI slots and could cause audio clicks and pops if they didn’t correctly release the PCI buss for other duties when requested, thereby preventing audio data from reaching a PCI sound card. Nowadays all PCs use AGP graphics technology, which provides faster graphics performance and avoids such audio interference problems. As an aside, music applications don’t use 3D graphics, so musicians don’t need an expensive state-of-the-art graphics card. Far more useful is a good-quality 2D dual-head model that supports two monitor screens, since most music software will let you place the songs arrange page on one screen, and the software mixing desk on the other, which makes working with complex multi-track songs far more pleasurable.
