In the price range I'd go with:
Intel i5 2500k
, the overclockable version.
XFX HD 6870
, more power than the 560 and less expensive.
But, like Slaymate said, you'll have to upgrade your motherboard, RAM, and possibly your power supply.
Also, you'll need to get a new copy of Windows if/when you change your motherboard.
