Hi everyone, I am just curious as I have tried searching on the internet and MacRumours as well but always end up with no definitive answer. Question: Does the AMD R200 or R300 series work with the Mac Pro? I don't really care about boot screen or anything, I just want to know if it will work since I don't want to pay a lot more for Nvidia cards for less performance. *P.S. I don't use Bootcamp or game on my Mac Pro, just want something to replace the 2600X since it runs so hot, boot screen doesn't matter to me. I don't want to flash anything, so if there any AMD PC Reference cards which work out of the box with OSX is what I want to know. Thanks for all and any help!
