Hi, if you are looking towards also using this for color grading Jeff is correct, consider a BMD HD DeckLink Extreme 3D+ for the HD-SDI out to the monitor. When DaVinci Resolve for Win is released in Q1 2012 you can then add a second. third, fourth GPU. At IBC on our alpha Resolve on Win system we had 20+ nodes at HD with four GPU's.
CS 5.5 works well with Resolve too using XML for round trip.
