Well I got no responses but in case anyone else is in this boat here is where I am at. I first cloned my start up drive so I could go back if needed.
I upgraded my graphics card to the Sapphire Radeon 9750, Mac edition with 3Gb of VRAM. Before installing the 9750 I upgraded to 10.8.5 and BM 9.7.5. FCP 7.0.3 and Adobe CC are all working fine. I just upgraded to BM 9.9.2 and everything still seems fine.
In the Decklink system preference my Decklink HD Extreme 3 card is recognized but there is one major gotcha to watch out for. Do not select extended Desktop. When I did this it sent the extended desktop to my main monitor and nothing to my FSI SDI. It was a bit of a nightmare to get my monitor back since I couldn’t access anything. PM me if you run into this.
