What component must typically be upgraded when working with high-end graphics for gaming?

When upgrading for high-end graphics in gaming, the video card is the key component that must typically be upgraded. The video card, also known as the graphics processing unit (GPU), is responsible for rendering images, animations, and video for the computer's display. High-end games often demand powerful graphics processing capabilities to deliver high resolutions, detailed textures, and smooth frame rates. Therefore, a more advanced video card can significantly enhance the gaming experience.

While other components like RAM, power supply, and motherboard can also be important in overall system performance and may need to be considered, the video card directly impacts visual output and game performance more than any other component. Upgrading the video card allows for better graphical fidelity and frame rates, making it essential for serious gamers looking to improve their gaming setup.
