About the PCI 3.0 x16 slots, will putting my single video card in the top-most(closest to cpu) have any benefits?

It is said to be
PCI Express 3.0 x16: 3 (16/8/4)

So does this mean the the top one is running at true x16 speeds, 2nd one at x8, and bottom-most one at x4? Or does this only apply when doing multiple GPUs?

I am using only a single GPU, NOT SLI. I wish to position the GPU a bit lower so that both it and the top of my mobo can receive better airflow from my side fan.

Thanks in advance for your comments!
