I WANT TO BUILD A SYSTEM THAT WILL GIVE ME THE FASTEST SPEED IN OCTANE. SHOULD I GET 2 GTX 480 OR 3 GTX 470? I READ ΤΗΑΤ THE CARDS SHOULDN'T BE IN SLI MODE. IS THAT TRUE?
p.s. Sorry for the caps!!
Thanks!!!!!!!

CUDA does not allow you to combine graphics card memory, so you would be limited to 1280 MB for the 470 and 1536 MB for the 480. I believe Radiance has stated that multiple GPUs do allow for bigger rendered images, which is actually pretty nice.
I'd think the 3x470s would give you a bit higher performance than 2x480s, but at the cost of 257 MB memory. This also depends on how well the final multi-GPU system scales (which we may see pretty soon).

I am thinking of combining 4 GTX480. I so the amazing videos in youtube:

Will the 4 GTX480 provide 2 times the speed of 2 GTX480?
Can we see a demonstration of the speed of 4 GTX480 cards from the developing team?? it will be an amazing promo for the software!!!

we only managed to get hold of 2 cards so we can't show with 4x yet.

YOU SHOULD!
As i am an architect and i am interested mostly in architectural visualization, my proposal is to prepare an exterior/interior of a building and realtime render it with 2 (or 4!) gtx480 cards. Then send the video to www.cgarchitect.com. Also work on the materials, as the libraries is an important factor for choosing a product. Could you work on a plugin for archicad or revit?
