Guys please provide info what hardware you were using in your video: http://www.youtube.com/watch?v=6ZmuI2xQp2M
For the GPU rendering? One GeForce GTX 480 and two Tesla C2050 cards.

sounds funny 
like who helped you move the furniture outside the house … ant and two huge strongmen
Well those particular Tesla’s are slower than the GeForce, but they do have more video RAM.

Hm, I stand corrected, apparently the GeForce was not used for the RT engine in this video, so the rendering was done just on the two Teslas.

but those tesla price is around 1.5 k for one card right?
They used to be quite expensive at one point, but I don’t know what would be their price now - they are quite old already.
Best regards,
