Perfomace question with Riser card + many GPU

[calvados]

I consider about new rendering machine, because I use 4 CPU with 9GPU now, it consume lot of Power.
Currently, we can use Lot of GPU (may be 8) with 1 Mother board via Riser card.
But this configuration is not good for data transfer rate, it is same as PCI-Express 1 more.
My question is This situation is good for Octane Render ?
I feel that multi CPU environment with LAN is more slower than this situation, therefore no problem for Octane Render.
I have no knowledge with inside.
Please inform real result or your guess.

PS.
