A promotional video from RenderStream, providers of multi-GPU systems for rendering and science, does a great job of also promoting OctaneRender on multiple GPU’s.

I am using Octane Render with 2 GTX 580 GPUs with 3GB of video RAM each, and I am amazed at how fast I can make a final-quality render.
But even more important, the speed now makes animations that I would never consider before, a distinct option.
GPU, as opposed to CPU, rendering is such a huge step forward for visualiztion.
