OK thanks for the info. When using a Multi GPU setup, does octane use all of them at once when rendering and how much of a speed gain can one expect from such a setup ? (1: 100%, 2: 175%, 3: 250% ?)

I'd love to see the results of one of the professional cards as they were actually built for GPGPU ...

Hi,

what would be the fastest card available today ? (Consumer vs quadro vs super computer tesla)
