What GPU is good for dual monitor gaming?

[SpaceX]

I have two 1920x1080 monitors, which gives me a resolution of 3840x1080 And i was wondering what GPU is good for gaming that is 100-200 dollars? Im asking for high settings at least 40 fps. I play games such as gw2,lol,bf4,dayz,planetside 2.

Do you really want to game on 2 screens. In FPS games it will be really messed up because the crosshair will be cut off in the middle of the two monitors.
If you still want to do it, a R9 290 or probably a 280X will be enough.
