Not sure if you already knew about them, but there are consumer X99 motherboards that include PLX8747 switches to mux 32 PCIe lanes from the CPU into 7 PCIe x8 slots, at premium of maybe $200 for the motherboard and $300 for a compatible CPU. (ASUS X99-E-10G WS)
The catch being that the 7 slots are next to each other, so you either have to make a custom water loop with single slot GPUs or use simple risers on half of them. But that's probably the best bandwidth you can currently get between >4 GPUs on consumer parts.
- highd 9y agoThat sounds amazing - do you know of any in particular? I can't seem to find any motherboards with 8 PCIe slots. Or do they need some sort of additional splitter?
- brigade 9y agoSorry, I was wrong, it's only 7 slots - ASUS x99-e-10g ws is the board I was thinking of.
- highd 9y agoStill pretty good - thanks!

With Ti series you don't have to cut the excess from the card either it seems, since there is no that pesky DVI port to saw off.
- highd 9y agoWow, thanks!
