You can get pretty amazing card of that age for peanuts. How much RAM and other specs are up for your consideration. Go to owc ( or any similar site) and look for any PCIe slot cards availability for replacement. It ia a museum piece but I don't do video or graphic editing on this one so it's good enough. It was a default one which I replaced some years ago with ATI Radeon 2600 XT 256 MB. So, let me tell you what I got at the moment in my prethistoric early 2009 (or late 2008, dual machine). I went to the site and via My Upgrades > Mac model > Video upgrades - the result came back with no cards, just cables etc.
