Suggestions for a good graphics card for this budget build

I'm looking at the Powercolor HD 6850 for $148 but I'm open to all other suggestions. I'm on a budget so I'd rather not spend more than $160.

My system would include:
i5-2400
Gigabyte H61
4GB DDR3 1333

Monitor: BenQ 2420HD running at 1080p

I'm not looking jaw dropping visual quality, just smooth FPS (>=40) for GTA IV and V, Crysis 2, LA Noire, BF3, MW3, Just Cause 2, Far cry 3, Fall out new vegas, Black ops, assassin's creed 2 and the rest etc...

Many thanks!
