If I am overclocking my 4770k (on my VII hero mobo) while connected my monitor to the integrated video card, will this affect the overclocking performance (temperatures, processor usage etc). Because when I am overclocking it and I am using the integrated video card it may require more voltage to achieve the speed, and increasing that voltage will increase my overall core temp. So is it better to OC my CPU when i put a video card in the PCI or it doesnt matter?
