69xx can run 4 monitors without involving external splitters and such. The 5th is just so you have options on which connections to use.
Just as the 58xx had 4 connectors, but was handling 3 monitors.
Also, this card looks a little shorter than the reference 69XX. Can't tell for sure though. Also can't tell if that's a BIOS switch just next to the X-fire. Hope to see more about this soon. Price wars might be a-comin'.
Is the HDMI port still shared with one the DVI ports?
