Both the 6870 and the 5870 AND the 5850 have quite a bit lower performance than the 570. The 560 won't be much worse than the 570; therefor, the 560 will perform better than all of those cards. But only time and benchmarks will tell. pipinhot2, that link shows that both the 5870 and the 6870 perform better than the 570, but benchmarks right there prove otherwise. Stats can tell you what the card is capable of, but it can't guarantee the performance.
