Hi All: I have a nice Mac Pro setup with a video wall. The video wall is just an extension of my desktop, so it's effectively just a big screen. I would like to take advantage of the wall for gaming and hook up an xbox or playstation. So, my question is what is the best video capture card for the Mac Pro? Particularly, which card introduces the least amount of latency so as not to hamper the gaming experience? The idea is I could play games and see the game in a video capture window, and perhaps stretch the window out to over multiple screens on the wall. Not sure if this is realistic, but would appreciate any thoughts/help. Thanks for any help!
