Look to the side of the unknown port on your motherboard. Next to it it should say if it is PCI Express *16.
Mine is a black slot ~ which is further away from the edge of the motherboard than the regular PCI slots.
The writing is quite small so if in doubt, take a pic of the slot, post it here as an attachment (Zip it up, or crop it down to the relevant slot with some surround) then i will take a look for ya
