how to use both onboard GPU and PCIe GPU ?

I'm not sure what you are asking. Are you asking if you can use both the onboard VGA/DVI connectors as well as the ones on the graphics card?

They can not be combined for better performance with a single monitor(if that is what you are asking)
OTOH, both adapters can be used to attach multiple displays.
