AMD i garantee will fix this. either that, or what i think they'll do will happen. HD 6970/6950 wasn't their origional release. It wouldn't surprise me if they did have a 1920SPU chip, the real HD 6970, and the HD 6950 will be phased out, or start coming standard with the 1536SPU's.
Be a banging idea for AMD to surprise nvidia and have a card up their sleeve incase shit gets deep for em.
