If the price is anywhere near the 460 it will be great but everything for the last year or more seems to be priced exactly where it should be for its performance give or take
supposly the 560 will be the 6950 killer because it will be place cheaper and its 15%-20% more performace then the 460 which is still a popular card.
Nvidia wants the 560 to be able to be overclock to high since this new chipset is suppose to make the 560 to oc further then any nvidia card (I got this from reviews talking about the new chipset for the 560)
I'm excited since it will be dx11, have lower temps and able to overclock further.
Only reason nvidia is finally letting the 560 out is because they were waiting to see what the 6900s could bring and I hope the 560 is toe to toe with the 6950 so I can probley oc to 6970 but its all a guess atm. We will see on the 25th of january to find out.
