- If the motherboard has built in graphics, you can use that while using that pci slot for a serial card.
- Does this motherboard only have one pci slot? That's not much.
- If the card comes with a driver, be sure it is compatible with the OS you run. On a PC with a motherboard that has a built-in serial port, it might not be Windows 8.
