At that resolution a HD7850 would be able to hit highest settings quite easily.
Guess I should elaborate, given the conflicting answers.
It will bottleneck in the sense that you can easily get more performance from the card, but at that resolution that performance cant be used. You will hit max settings in games, and the GPU will still be able to perform better.
Running that graphics card on a 1080p screen wont bottleneck it, because then the card becomes the bottleneck (in some intensive games), as it will hit its max performance trying to push that many pixels.
