Probably not. 7xxx brings support for 4096×2160 @ 24p which is in HDMI 1.4a spec, but I am assuming you don’t have a display or content for that.
Another consideration is MadVR renderer, if you plan to use. You’ll be better off with NVIDIA on that front. If you can wait, maybe see what NVIDIA rolls out in the 6xx series for the lower end. The GT 430 is a pretty good card for MadVR and 1080p/24 content and display.
