PCI-E 3.0 x8 is the same as PCI-E 2.0 x16, so he's looking at a 2 FPS drop at worst and a 0.0 drop at best. That's within margin of error, mate.
No, only within the same generation.

It was meant as a more general information post, not a OP's specific situation post.
*So he doesn't end up in the position I'm in currently*

Compute tasks? Can you specify? Will i gain anything from having a second card plugged in? Crossfire/Non-Crossfire.

For normal use/gaming stuff no. For rendering/mining/boincing yes.

Yes, except PCI-E 2.0 x32 doesn't exist.

I know that, just giving a toe to toe compare

Having a GPU support PCI-E 3.0 doesn't mean it will run at 16GB/s. Cards are far from having 16Gb/s bandwidth yet. Right now it seems like just marketing materials. To fully utilize PCI-E 3.0 bandwidth would be SSD RAID on PCI-E 3.0... at first before GPU does in near future
