I would make a couple of small changes:
-Spend more on GPU and less on CPU. If you're going with AMD then something like a Phenom II X4 965BE will be cheaper and still good and spend the money on a 550ti at least.
-If you're not going to SLI/Crossfire you can lower the price by picking another less powerful PSU. Something with 500watts from Corsair,Antec or Seasonic will be more than enough for that build and will be cheaper.
Intel has better CPU's at the moment specially for gaming. The one satyamdubey mentioned is pretty good for it's price and can go against AMD quad cores. If you get something like a i5 2500 then you've already got enough CPU power to handle everything you could want
