So,have been trying to find out some "before-after" performance of the said card for macpro. Havent found much or anything. It does some of the renders in FCP in realtime but even the full list of what it does seem to be hard to find. Let alone some comprehensive speedup charts. Getting the atis 4870 for my mp1.1 after SL comes out but thinking how much extra oomph you could get for 1080p editing. Also,how would the setup go in that case? I mean I have a 30" acd atm,and could use my 20" acd as a second display and I propably would get a small&affordable fullHD LCD to be used as a reference monitor through the HDMI of the blackmagic. So would the 30" be connected to the ati,and the 20" to blackmagic? What if I would not use the 20" or have the TV in the hdmi : would the card still perform and do all the extra calculations or would I have to move the 30" to the blackmagic to get the card to be engaged.
