If both cards have 1gig each you only really have 1gig of ram period. The 2gig thing is something graphics card manufacturers seem to be able to keep getting away ( marketing ploy ) with when in actuality there's still only one gig available. If you want 2gigs avail you'll have to buy a 4gig card. Same thing with cross fire or SLI. Two cards don't mean twice the memory to use.

You've answered it yourself, 2GPU with 1GB each = 2x1GB=2GB

If a game requires 1.1 GB of vram , u r likely to get a vram bottleneck.

Just to explain it a bit. What happens is you buy a card like a 5970 which has 2 GPU's on board. This is to all intents and purposes the same situation as far as memory goes as running 2 cards in Crossfire.
Each GPU or card has to have a copy of the same information in it as the other one, so they both know where they are up to.
This means that if you have a 1GB card and add another one you still only actually have 1GB of ram available as by the time the memory on card 1 is full card 2 has an exact copy as well.
