I would imagine those cards are the equivalent, more or less. The 580 GTX seems to be faster than the 6970, but it also costs more.
The best places to check would of course be guru3d, anandtech, tom's hardware...I don't keep up with the Nvidia side of things much these days...good cards, but I've got an Ati for now, so I don't see the need to know what's going on in the 'green camp'.

As far as your second question is concerned, there is no problems that I'm aware of mixing your Intels, Amds, Nvidia's or Ati's.
