I don't recommend that combo, It will work but you won't get all your moneys worth. In my opinion you'd be better off going with a 7770/7750, both are good gpu's and you can play most games on med-high settings (max everything but shadows).
If you overclock a bit it will be fine. The bottleneck will move between the CPU & GPU depending on the game but is likely more on the CPU side but an overclock would even it out.
