Nice. Thanks for the report.I haven't seen it confirmed anywhere else, so I just thought I'd mention it here: I picked up a pair of active Mini-Displayport to DVI single link (Accell B087B-006B) and can confirm that they work on a 2010 Mac Pro with a 5870 card. I can drive three DVI monitors at 1920x1200 by using two of these and the DVI port for the third one.
