VRAM Usage - 6970 (2 GB) vs. GTX 580 (1,5 GB) vs. GTX 580 (3 GB)

yes, but that doesn't mean they can't have both GPU accessing the whole memory (as the memory is on the same card, the accesing speed should be faster than accessing the other GPU's memory via a SLI link).

is highly improbable, but as none of us really knows the way the hardware of dual GPU works, we can't have a say in this.

that's why I said we need to dig this up.

Each GPU maintains it's own frame buffer, rendering data is duplicated in each frame buffer. VRAM is not pooled.
