Is a gtx560 ti a good upgrade from a gtx 275 video card?

my gaming pc is starting to get slower for games, its not that slow but i would like to be able to play new games on my pc, is the tx560 ti card much better than the 275, is it worth th eupgrade or should i wait for newer cards to come out before i upgrade my parts, my video card is 2 and a half years old btw|||Hell yeah gtx 560 is a hell of a card u know nvidea models who have x marks gt X are made for extreme gaming and u will run ultra high graphics even in 3d mode with this card :D
