I know a card that is currently going for 200 is the 760, it wouldn't run all games on Ultra, such as BF4 where it will surely choke, but it is an overall good card for a majority of the games.
Plus, I'm not sure about your CPU. I don't know if it would bottleneck a 760, but I'm sure someone else could help with that.
My conclusion is that if you're playing battlefield 4 or crysis 3, save up more, and invest in a 780, and possibly a later generation i7.
