[quote="Haldi"]Turning off Crossfire will deactivate Eyefinity aka Single Large Surface/quote]
Huh? disabling crossfire also disables eyefinity?
I never found this to be the case when I was running 2x 5870E6 cards, I could run eyefinity on 1 card while the other was used for independent monitors, disabling crossfire did not disable the eyefinty features.
As suiken_2mieu points out, disable crossfire, this will allow you to output to 12 displays.
If you wish to use Eyefinity with 12 monitors then take a look at the Zotec Dual HDMI adaptors...
http://www.wsgf.org/gallery/zotac-dp-du ... ent-243295These take DP in and spit a dual HDMI out , thus turning 6xDP outputs into 12xHDMI outputs, all with eyefinity support, the PC would detct 6 monitors, but each monitor would count for a pair of monitors.
