An amazing improvement - running an early 2009 Mac Pro

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.
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.
Summary: Early 2007 MacPro 1,1 with superior results. I can play Minecraft with all graphics options maxed. This is the kind of upgradability that is why I bought a tower. Unfortunately, Apple still won't let me load OSX 10.8 now that my old computer is at least as fast as a cheaper new machine.
