Being a HD5870 owner I've been wondering about this myself,
I think I have the answer, "NEW CUSTOMERS ONLY"
It seems mixed resolution eyefinity is ONLY supported on R series cards
Pay close attention to
Quote "All AMD Radeon™ R7 Series and R9 Series graphics cards support mixed resolutions."
I can only believe this has been done to push sales as many HD5000 to HD7000 series cards could handle Mixed eyefinity...
Disapointed in you AMD
