Oh, I see. When nVidia says, "Quad SLI", they mean dual, dual GPU boards. As up until now there's not been motherboards with 4, 16x PCIe slots.

But their SLI 2.0 spec does support 8+ GPUs. Wish I could find out if someone has tried this yet.

EDIT: Anyway, it doesn't matter for what I want to do. I'm looking for video compression using CUDA, not SLI for gaming. CUDA is fully supported on as many GPUs as you can get into a machine (found a mention of 12, and actual implementations of 8 GPUs: http://estoniadonates.wordpress.com/our-supercomputer/ ).
