Pretty much what he said.
Also, my good friend went directly from a 260 192sp, which got rma'd and a 216sp sent back a week before he got a 560 Ti FPB from the last EVGA competition and the upgrade was a decent one. The 260 is still a powerful card, but the 560 Ti will just have nicer eye candy like Brett said. Also supports DX11.
I actually have his 560 Ti FPB sitting here in my system as my card right now, and another GTX 275 here as well. I think I'll do some comparisons tomorrow.
