Yes and no...Yes you can crossfire them, but no the VRAM does not pool, it mirrors. When you crossfire them, you will have 2gb VRAM, the lowest amount of the 2 cards. If one has higher clock speeds than the other, it will usually automatically sync them to the lower speed.
You would be much better off with a single more powerful card as not all programs support crossfire and some actually have decreased performance with it. Not to mention probable micro stutter issues.
You could get much better performance from any current generation card.
