Well considering a Titan uses 350 watts and Rogue generally uses less than 15 watts you wouldn't even need to pack them in all that tightly for some pretty cool results. My brain can only imagine though how awesome it would be to have equivalent wattage from Wizard as a few Titans packed into a box. 20x cards * 6 = 60x rogue chips equivalent to 6 titans. 60 * 300 = 18 Gigarays per second.
With 18 Gigarays you could have 18,000 Megarays / 2 megapixels (1080p) = 9,000 rays/per pixel /s divide that by 30 frames per second and you're looking at 200 rays per pixel per frame. That would be a little grainy but pretty close to a production quality rendering in real-time.
