6870< 5870 ?!
Yup.
AMD decided to change their naming system (not quite sure why, but there we go) so that the 6800 series is the successor to the 5700 series. The 5800 series successor will be the 6900s.

The lack of nVidia offerings in comparison is explained in the review - quite simply, without getting hardware to test the way other review sites do, it's too costly to go out and buy them. I did because I wanted to go Surround, then saw that 2GB cards were probably going to be an improvement so dropped some more money on 'em. But the Surround review was done under my own steam, as it were.
