I have a 2006 Mac Pro and have been wanting to update to OS X Mavericks but I can't because I have a Radeon X1900 graphics card and that is not supported any more by Apple. I have OS X 10.6.8 running so I have the software to upgrade it but the question is can I update to Mavericks if I get a supported graphics card? Do you think there might be other issues that would prevent me from being to update?

P.S. Yes my Mac Pro is 64-bit.

Which model of Mac Pro do you have? If it really is a 2006 model, that sounds like a MacPro1,1, which isn't supported after Lion (10.7) as it has 32-bit EFI even though its CPU(s) are 64-bit. The fact that you have a Radeon X1900, which was an option on the 2006 model, suggests that you may well be out of luck when it comes to upgrading.

Mavericks system requirements are here - as you can see, only early 2008 and later Mac Pros are supported. That said, if you're that way inclined, there are ways of getting Mavericks working on unsupported machines - see this guide, for example.

You can confirm the exact model number by checking About this Mac -> More Info... and then verifying the Model Identifier.
