Using Intensity Pro with FCP X

What functionality does the Intensity Pro card have with Final Cut Pro X? What I'm looking for is to be able to attach an HD video monitor via HDMI as a program monitor as I'm working on an edit. Also, can you capture video in FCP X? The product info on the Intensity Pro really doesn't say what works and what doesn't in FCP X, only that it's compatible with Final Cut Pro. What will it do in FCP X? And more importantly what will it not do in Final Cut Pro X.
