"It uses the VRAM from both cards, but because each card is doing alternate lines, each card is using it's own VRAM. "
You're thinking of old SLI from 3dfx---when it meant "ScanLine Interleave" ---drawing half the screen on one card then the other. In those days, 2 8MB Voodoo2s would actually have more than 8MB total memory to play with.
Todays SLI (Scalable Link Interface)/Crossfire is AFR based (alternate frame rendering) which is why each card has to have the same texture data on board, thus 2 4GB cards only have 4GB texture memory, not 8GB like some think.

Thank you for your articulation on that.
Does anyone know when this will be playable in central europe? It won't start for me yet, purchased on steam and I'm in Germany. I've read somewhere 7 p.m. CET which would be now but it also might be 7 pm UK time. Anyone?
Well i'm in Switzerland and have been playing for a couple of hours already. So if you are ni Germany then you should also be able to play.
