Been thinking of adding a 3870 to my GeForce (Yeah, I thought it would be faster than the stock card when I got it as a BTO option ) for faster pro app performance and potentially the use of three monitors if I decide to go that route. I'm curious if anybody's using these two cards already, and if they are, is it noisier that way? Is there a certain arrangement they should go in (in other words, which card goes on the bottom?) for the best airflow solution? Second, I figure few people actually use the analog output on the 3870, but if any of you do, and if any of you use Final Cut, can you use that analog output for color-accurate external video monitoring? It would be cheaper than buying a DV deck just to output through composite, and make the card's price completely justifiable, if that worked.
