Any difference in performance between connecting a display to GPU port and graphic out port on motherboard?

Question

Say I had a GPU on one of my PCIe slot, but my display(s) are not connected to the GPU out ports, instead, they're connected to the Thunderbolt out port on the mobo.

Will the system receive performance benefit from the dedicated GPU, or will it just use the integrated GPU on the motherboard?

Thanks.

Neither... normally when you install a standalone card in a PCI-E x16 slot, the motherboard's onboard display ports are automatically disabled.  In very rare cases the motherboard's integrated GPU might still function if you connected something to that port, but usually not (I'm talking about traditional DVI, HDMI and VGA ports on the motherboard).

In the context of video/graphics card, the Thunderbolt port functions as an input rather than output port (to connect external cards, and your monitor would be connected to the output port on those cards)

You read it here...http://en.wikipedia.org/wiki/Thunderbolt_(interface)
There seems to be no real difference  except if your using a video "card" your sure to get better performance from it...than any Integrated GPU no mater what "port" you use pn the mother board.
