Quick question about motherboard slot

[technoob1111]

Hi guys, i need a little bit of help. I was wondering what type of slot is in between the two video cards in the following picture? I believe that the 2 white slots on the right of the right video card are PCI slots. I can't figure out what that middle slot is.

Thanks a lot for your assistance!

Judging from the slot size, it is a PCIe 8x slot.

Pictures comparing them to standard PCI and PCIe 16x appear to be hard to come bye so sorry for the low quality.

The top is a PCIe 16x, next comes PCI then a PCIe 8x slot.
The bottom most slot would be a PCI-X slot.

The next picture is just to show you the size of a PCIe 1x and 4x connector relative to 16x and PCI slots.
