I'm with Beltzy on this. Not only all the things he mentioned, but the GTX560TI also uses around 40W less under full load. (170 vs 210 going from memory.) So in addition to being cheaper and nearly as powerful, it won't raise your electric bill as much or put as much heat in your room. And it's still good enough to handle nearly all games at 1080.
If you've got the money and don't care, the GTX570 is a good card. But I think for most of us the GTX560TI is just as good.
