Which card would you use if you want to enhance audio performance while gaming or producing music?

To enhance audio performance while gaming or producing music, the ideal choice is a sound/audio card. Sound cards are specifically designed to manage audio input and output, offering superior sound quality, better audio processing capabilities, and often additional features such as surround sound support, sound effects, and improved audio latency.

These enhancements are particularly important for applications like gaming where immersive audio can significantly improve the experience, and for music production where accurate sound reproduction and the ability to connect professional audio equipment are crucial. A sound card typically provides dedicated digital-to-analog converters (DACs), which render high-fidelity audio signals with less interference compared to integrated audio solutions found on motherboards.

Other options listed do not serve this specific purpose. A video card enhances visual performance; an expansion card is a general term that could refer to any additional card installed in a computer and does not specifically imply improved audio; and a TV capture card is designed for capturing video signals, not for enhancing audio capabilities. These functionalities make sound/audio cards the best choice for anyone looking to boost their audio performance.
