so you mean to say theres no on board VGA output in a P55 motherboard,
Correct, P55 boards don't have on-board video capabilities. On H55, H57 or Q57 have that option with an appropriate Intel i3 & i5 CPU's. Which means, you can use an i5 760 on the H55 and have on-board video, since the chip doesn't support it. You would need to have a dedicated GPU.
