x16 is sixteen times more bandwidth than the x1
the cards may be exactly the same in reference design the x16 just communicates with the motherboard better, as it is a larger bus width..
pci-e 1x is twice as fast as the standard pci slot.

it just wouldn't use all of the available slot physically and it wouldn't communicate as fast with the motherboard.. you likely would get degraded performance in comparison to the x16 counterpart.. but it wouldn't hurt anything to run a 1x card in a x16 slot..
No, it will run fine. Because the GeForce 8400GS is one of the slowest current generation video cards out there. It will not bottleneck the PCI-E x1 slot. At all.
Basically it will allow you to play the latest PC games.... On the lowest settings and lower than 1024x768.
