Well the title says it all.... I am going to need to boot to different drives pretty regularly, and currently my 5770 doesn't allow me to view the bootloader display. I need this to be compatible with Mavericks as well. I have a 1,1 currently running Lion I'm thinking about the Mac Edition 7950... I just need to make sure it works for Mav and the default OSX bootloader. Other than that, I need 3 display support... but maybe not as I could always just stick my 5770 in there and just use it for the extra ports. I would love to hear a few suggestions... my price range is up to $300... maybe $350 on ebay. Thanks for your help guys!
