There is basically no difference within margin of error.

Even if you were sli'ing two cards that could take advantage of the bandwidth, you'd still have twice the shaders and VRAM.
The ram does not double, it mirrors.

if you SLI two graphics cards that got 1Gb of memory each, the total amount of VRAM you will have is 1Gb, not 2 Gb.

Actually the total amount of vram you'd have is 2 x 1GB. When you say you'd only have 1GB, you're talking about the effective capacity, not the total amount

On the topic, though I think the only card(s) that might suffer a little at 8x would be 590/6990. And two single gpu cards in SLi will be fine at 8x/8x. Heck even 4x/4x would probably only lose you like 10%.
