I think I've seen it somewhere, but couldnt find it.. Im looking at PCI-E extenders and finally found something, so now Im wondering what is the maximum amount of GPUs that can be used? I think I've seen the number eight somehwere, but would would 8 x GTX690 work or are those counted as two?

i´ve been looking for PCIe-Extenders, too,
but was not happy with the result.
Which ones did you find?

Currently there is no limitation of the number of GPUs in Octane. Realistically though, you will hardly be able to plug in more than 8 graphics cards into your system, which results in 16 GPUs. We have tried Octane on a 16 GPU machine and in works fine.
