Like Madpistol said this is an Nvidia site so you get some bias. If you want facts just read the Anadtech review.
If we take a straight average at 1920x1200 and 2560x1600, its performance is more or less equal to the GeForce GTX 570. In practice this means that NVIDIA wins a third of our games, AMD wins a third of our games, and they effectively tie on the rest, so the position of the 6970 relative to the GTX 570 is heavily dependent on just what games out of our benchmark suite you favor.

Personally I went for the XFX 6950. I've always had Nvidia before this and besides this being an awesome card I just wanted to try ATI out. Everything I've tried so far has been very smooth. Not to say that the 570 wouldn't be like that, but I know fur sure at 1920x1080 the 6950 performs wonderfully.
