Would a PCIe 3.0 x8 slot bottleneck a single GTX 680?

Does it really need to be PCIe 3.0 x16?

 

[AMD Radeon]

No It won't, even if SLI mode.
Here's the scaling of Different PCIE versions and modes.

No pci-e 3 x8 will never bottleneck a card
the bandwidth of pci-e 3 x8=pci-e 2 x16

no cards built so far can reach the speeds of pci-e 2 x16
