so, about on par with regular SLI.
I think Nvidia needs to do some work on SLI.
The G92 is good, but still doesn't scale all that well when you put multiple ones together.
I'm not sure I like the idea of two PCB's for "one graphics card" either.
looks a bit like a repeat of the 7950 GX2
the PCB's were so close together, so that didn't help cooling.
at least with regular SLI/crossfire, there is usually more breathing room for the cards.
