Usually, no dedicated graphics card is required just to install and run Photoshop. Photoshop can run on many systems using integrated graphics, especially for basic photo editing. A dedicated GPU mainly helps accelerate certain features such as smoother zooming, panning, some filters, and other GPU-assisted tools.

The real requirement is whether your computer meets the Photoshop version’s minimum system specs, including supported graphics drivers and enough RAM/CPU performance. If your integrated graphics are older, Photoshop may still install, but some accelerated features could be unavailable or slower.

So the answer is: you do not necessarily need a separate video card, but performance and feature support depend on your exact hardware and the Photoshop version.
