    Mac Pro 5,1 (Mid 2010) & AMD Radeon R9 280X 3GB - 4K Support??

    here is my current setup. I'm leaning towards a yes for my question but I do not know the answer absolutely so here goes.. wondering if this video card will support two 4K Displays via the mini DisplayPort outputs? that is two displays @ 3840 x 2160 resolution running at 60Hz I'm looking at...
