WHY does an 8800GT crush 8600gt SLI'd?

Hello, just wondering the reason(s) why a single 8800gt apparently crushes 2 8600gt's SLI'd. I've read countless posts and articles stating how an 8800gt mops the floor with 8600gt's sli'd, but I cannot find anyone actually explaining why this is true.

Maybe I'm missing some obvious reason here, and if so I apologize.
Here's a comparison chart http://www.nvidia.com/page/geforce8.html

Is it perhaps the 8800 gt's 256-bit mem interface, or maybe the vast difference between their texture fill rates?

The 256bit interface and faster transfer rate mean the world in video cards and the 8800gt is a beast.

112 SPs for the 8800gt

The most significant thing:

The 8600gt has 32 Stream Processors, while the 8800gt has 112.

Not to mention that SLI doesnt scale perfectly

Yeah, what's the scaling with 2 8600's? Somthing like 20 - 30% on average? Unless you are using the highest end card sli is worthless and deffinitely not cost effective.
