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: This product it's an excellent replacement for the 256 Gb video card that came with an early 2008 Mac Pro, specially when new software programs required are requiring better video cards with more memory and processing power. This is a pull out, plug in card made for newer Mac Pro's and even it's not mention for this model of Mac Pro, it's a perfect fit. I've throng some heavy tests to this card computer combination and it works like if it was made for this computer.
Summary: Bought this to run in Crossfire with my first XFX Radeon HD 5770. The two worked really well together for just over a year when I built a new computer last week. As a single card it was fantastic even when I purchased it as a 'budget' card at $150 the first time. As for the brand, XFX, I've only trusted them or EVGA for their reputation. I've never had an issue with the cards myself, including during several months of overclocking their processors and memory.
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.
