I don't see why single card isn't measured on how many PCIe slots it needs to be plugged into?

yea, but that's dual slot, mostly for cooling, not for how many die are on the PCB.

Who cares how many cores or heatsinks or PCBs it has. If it can plug into any ol' PCIe 16x slot and work at full performance, it should be single card.

you might want to refer to it as PCI-e 2.0, as most new motherboards are using that standard. PCI-e 16x is dying, IMO.
