An amazing improvement - running an early 2009 Mac Pro
9 August 2014
Summary: An amazing improvement - running an early 2009 Mac Pro, photo editing software loads significantly faster than with the original card. Easy to instal The only suggestion I have is that the instructions don't tell you to move back the card protector on left hand side of the slots, near the front fan.
Not OEM, Re-flashed but worked perfectly! Just need Active Display Port adapter instead of mini display port adapters!

Summary: Excellent video card. Didn't realize just how loud our Mac Pro had gotten with the fan running all the time to keep our older video card cool while it was slowly failing. This card runs very hard. However Keep in mind that under this listing people are selling the re-flashed PC cards for use on Mac's. Some of these may not be full Mac Cards and so they don't have Mini Display Port plugs on the back.
Great product. Fast delivery. Easy installation. No hassles.

Summary: The ATI Radeon HD 5770 1 GB works great in my old MAC Pro 1,1. (Had to replace the original graphics card, which was going bad and freezing up my computer). Easy installation. Up and running right away. Noticeable performance improvement with this new card.
Summary: I was considering upgrading my Mac to one of the new systems (the one that looks like a black tube). As a video producer, I needed more power. However, Apple kept delaying the release of the machine, and so I would get this device to take care of business until they finally get here. Well, now I may not bother to get one.
Wish it was the correct card. Bummed it was advertised as an apple card

Summary: This was advertised for an apple graphics card. This graphics card was designed to fit a pc not an apple mac pro. I had to send this back because it did not fit my mac pro. The housing on the card had a wing on the end which would not fit into the slot of my mac pro. So, I can't review the product because it did not work in my computer.
Summary: I just installed this card in a 2009 Mac Pro, quad-core 2.66 Nehalem and the overall performance of the computer is improved because the graphics refresh is so much faster. This was definitely an excellent upgrade to a computer I expect to be using for the better part of the next 10 years. Installation was a snap, came right up. Totally impressive.
Summary: The original video card (NVidia GeForce 7300 GT) worked fine until I needed to run a Win XP virtual machine in VMWare 6.0 (to run a CAD program). Moving objects during design was choppy and slow. A quick search found recommendations for upgrade on the Apple forum and here at Amazon with this Apple branded ATI Radeon 5770 1GB video the recommended upgrade path for the MacPro 1,1. I presently run OS X 10.7 Lion. Installation was easy and not complicated.
