I have an Asus mobo P8P67 and need a 4k graphics card

I have an Asus mobo P8P67 core i5 quad 2500k processor currently with a Radeon HD5700 graphics card. I wish to upgrade the card with 4k support for 4k monitor (not gamer) just for enhanced graphics. Is there an AMD 4k card that is compatible with my current mobo?? Any suggestions would be appreciated.
