HP 584217-001 ATI Radeon HD 4550 PCIe x16 512MB graphics adapter card
Does anyone know if this video card will work on the MacPo 2006 upgraded to 3.0GHz, 32GB Ram flashed to 2.1, OS X 10.5.7?
The Mac Pro First Generation is an Intel Xeon-based workstation computer manufactured by Apple Inc. The first generation model includes the machines from 2006 through 2008.
It should work, since it’s just a graphics card. Honestly, give it a shot! If it doesn’t work, you can keep working on fixing it, or just sell the graphics card!
Maybe also try getting something more oomph-ier, if you’re going to be using dedicated graphics.
