Will this work for Dual Monitor

Hi, i read some posts that saids you can use Dual Monitor if u have a Onboard VGA and a Graphics card, is it?

As long as u have 2 VGA port, and it will works, is it??

It al depends on the actual mother board that you are using. most resent boards disable the onboard monitor as soon as it detects the PCI/AGP card is being used by a card. It would be more helpful if you posted the Motherboard and Video card in question.
