The killer feature for me on this card will be full bitstreaming of HD audio streams over HDMI. Because it is based on GF104, it is logical to assume it will include this feature.

I would have bought a GTX570 already, but they have not added this feature into GF110 for whatever reason and that is a huge dissapointment. This upcoming GTX560 will be the first card to offer upper mid-range performance AND include the audio bitstreaming.

I know I am in the minority as one who runs everything thru a A/V reciever, but this is a make or break feature for me. The 6950/6970 are also appealing because they include this, but I will wait to see how the GTX560 stacks up before deciding.
