I too thought it looked like 3 wires at first until I looked again. It is only two 1 6pin + 1 8 pin. Just must be the way they had the wires situated.
Also did anyone notice that the guy running the demo happened to keep switching the modes during the really intense tessellation parts? It was either him doing it or that is the way they had it set up to run.
I the parts that it did run with full Tessellation it did look a little choppy at times. I do think that it looked a little smoother than my single 5870..... but not too much. Not enough to make me really impressed.
So let's say for a second that this thing really does beat a 5870 by 36%. Well I wouldn't be surprised it only is coming out half a year later. If you ask me that number wouldn't be that impressive for 6 months later.
But I still like the idea of the technology that they are using. I also think it will be a great addition to the world of GPU's. It will keep things moving forward that is for sure!
But If I was that confident with it's performance and I were Nvidia. I would have left the FPS counter on the bottom and the top..... still left out there for all to see. But they didn't makes me wonder.
