surely it would be getting results somewhere in between a single 3870 and a crossfire [two singles in cf setup?]
If your thinking was correct...could you explain?
Easily man...

A LOT less latency than regular cross-fire.

You see, regular cross-fire has to do a majority of it's communication through the chipset. Meanwhile this card has it's own splitter and does it's communicating all on card. As such, there's less latency all the way across the board.

ALL current multi-gpu set-ups have to duplicate data for each gpu in ram. They have to, because both gpus need the same textures and shader information as they both work together to render the scene. Essentially they all run as if they had the same amount of ram as the lowest card does. That's just how things have to work currently, and why I believe the R700 will have to have an external memory controller for the MCM package.

To sum it up, this card is like a lower latency CF set up.
