My game is using close to 1.5GB of video ram, because the game can't see the other 1.5GB on the second GPU in my dual GPU card.

People that have 2GB cards can confirm that their game is using close to two GB of video memory.
I think with 2GB you should be fine, but now, with all this 3GB cards on the market, I wouldn't spend a penny on a card with less then two GB per GPU.

The more you have, for this game, the better.

I confirm, the game uses nearly all of the 3 GB of VRAM, it tops up at >90% occupancy of the VRAM.
