Meh, depends on the game. I can run Skyrim (with texture enhancement mods) and BF3 with everything completely maxed out on a GTX 460M crammed into a laptop case. A 560Ti is a few notches up the ladder from that, and being in a desktop case, it should have better cooling as well. Some games may still tax it, like Metro 2033, but you'll be fine with the majority of newer games. There shouldn't be anything that you can't run at all.
