The first section of the connector on that card is not part of the PCI
connector. The reason the PCI connector is in 3 sections on the card is
because the card supports both 3.3v and 5v operation. The arrangement of the
two sections of the connector on the motherboard determines which voltage is
used. See http://en.wikipedia.org/wiki/File:PCI_Keying.png

They generally are pretty precise. PCI means PCI, PCIe means PCI Express.
Any mention of x1, x4, x16 etc means PCI Express. If in doubt go to the
manufacturers page, for the card above:
