Hello, I just bought a MacPro (2006) for $250, and am looking to upgrade the graphics card (on a budget) but am looking for one which is compatible with OS X Yosemite/El Capitain without reducing any of the performance.

Currently I can not install anything above 10.7, but from what I have read, it is possible with the proper graphics card (). I am not looking for gaming intensive stuff, just a good desktop, with 1080i capability (& VGA if possible).

From what I've read, some cards are not 'metal-compatible', so I want to make sure I get the right one. Any help or point in the direction of which graphics card to purchase (less than $80 hopefully), would be very appreciated.

The board itself is capable of having a 64-bit EFI and operating system, but the EFI given to it by Apple is only 32-bit.
