Except if AMD holds to its promise with Mantle we may see games being handled at higher resolutions than before.
BF4 will be supporting Mantle and the 7xxx range AMD cards have support by default.
If AMD is true to its words about 9X the drawcall performance over DX11 then one could guess that games using Mantle may be more easily handled at higher resolutions even if their fidelity is par with DX11.
