My understanding is it's a dual GPU card and each GPU has 3gb of vram. Which means the memory is not stackable so In reality is only has 3gb of vram.

That applys if you crossfire two 7970s however this has 6gb built into one board and is shared between both.

I could be wrong but everything I'v read says in a dual GPU card the memory is halved.

You may not be wrong, although I was just under the assumption that it was shared although not actually halved,

Its a good thing then that you remembered that because I sure didn't, it seems like a shady marketing tactic. Atleast with crossfire the double memory is only an assumption and not actually stated as such.
