It says it has a PCI 3.0 slot, but it's not marked. Which one is it? I have an HD 7770 that needs a 3.0 slot. It's currently in the red PCI slot (second from the left) that looks like the white one. This seemed the logical place for it, but the slot is unmarked so I'd like confirmation that this is indeed the 3.0 slot.
EDIT: GPU-Z says the card has a PCI-E 3.0 x16 @ x4 1.1 I'm not entirely sure what this means. I know the tooltip says it'll change when the card is under load, but so far it hasn't changed.
