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: 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.
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.
Summary: Nervous on if this would work for MacPro 2006. It has mini-DV ports that the original card did not have. I bought a cable to convert and everything worked fine. I did have some HD issues and the computer would not start after setting up this new card but the genius bar came through and the computer works as well or better than it did out of the box. This card is so quite. DataVision customer service was great.
