Can you add a discrete graphics card to a system that has integrated graphics?

Yes, you can add a discrete graphics card to a system that has integrated graphics. When you install a discrete GPU, the system typically defaults to using the new card for graphics processing, while the integrated graphics may be disabled or remain available for specific tasks. Ensure that your motherboard has the necessary PCIe slot and that your power supply can support the new graphics card. Additionally, you may need to adjust settings in the BiOS/UEFI or operating system to optimize performance.
