Driver upgrade for AMD Radeon 5770 Graphics Card
I have a 2008 Mac Pro, running OSX 10.8.5. Just installed AMD Radeon 5770 graphics card (Apple says this isn't supported; users I read said it works despite what Apple says in knowledge article (http://support.apple.com/kb/TS3477). When I restarted, the system said my card was a Radeon HD 5000, not 5770. AMD's web site not clear about driver upgrade (and I believe I have to do this, since I took out the old graphics card (ATI Radeon HD 2600 that came with the Mac Pro at purchase). Didn't get a clear answer, yet, from Apple support. Anyone experience this? Does anyone know which driver to manually download from AMD's site? It's not clear, and they also suggested, talk to Apple to get driver support. Here's where I went, and found the choice not clearly mapped out for the Mac (and their autodetect software works only for XP:

Thanks.
