Hi All: I did some searches, particularly the compatibility list of flashed cards: http://forum.netkas.org/index.php/topic,371.0.html I didn't see that anyone got these cards to work. Sorry if I missed an obvious spot. Anyway, has anyone gotten ANY 5 or 6 port (e.g., eyefinity) cards working in ANY mac pro? More specifically, gotten the card to work and support all/most of the ports? I have a 2006 Mac Pro and the new 12 core model. I'd love to get this single slot 5770 working (or any 5/6 port single slot card) working: http://xfxforce.com/en-us/products/graphiccards/hd 5000series/5771.aspx Thanks for any help or pointers!
