I hear rumblings in the back of my head saying a PCI-E device can be plugged into any PCI-E slot that it will physically fit. i.e. a PCI-E one sound card will work plugged into a PCI-E 16/8/4 slot. Is this correct? I'm asking because a lot of P55 boards out there will block a PCI-E 1 connector because it sits next to the PCI-E 16 video card slot, most video cards today are double slot size units. I want to keep my ASUS Xonar Essence sound card which is PCI-E 1.
