Broken Built-In VGA Port, Fix it or buy New?

A storm hit our place and flood came in our house and my father was in a hurry in disconnecting all the peripherals of my computer. Unfortunately, he doesn't know how to unplug the VGA Connector of the monitor because of the lack screw. He pulled it with force and resulted to breakage of the built-in VGA/Monitor Port.
I still need to use my old motherboard but it has a broken VGA Port. Should I buy a separate Video Card, should i ask the technician to just replace the broken part or should i buy a new motherboard?
