Apple ATI 5870 - ZML Standalone Kit MC743ZM/A Review

Despite Apple insisting that this card does not work with the 2008 Mac Pro (MacPro 3,1) I decided to take a chance and order the card because the machine meets all of the required hardware specifications. I looked at the actual technical requirements like slot type and power availability based on the AMD/ATI information, not just what Apple officially publishes. I put the card into the machine and it works great. I ran a simple OpenCL ray tracing application and was very pleased by the performance. One thing that is not explicitly made clear without research is that the card requires two 6-pin power connections. As such, it is not possible to install more than one of these cards in your computer, at least on the model I have, however the instructions indicate that the situation may be the same for the 2009 and 2010 models that this card is advertised for.

Also, the card I received looks like the card that is under the smaller one as shown in the picture. It is around 12 inches long and will span the entire length of the PCI bay. For nontechnical people, these are double-wide cards and you should probably install the card in slot one, the lowest slot, if you need to use the other PCIe slots as it will cover the adjacent slot if installed in slot two or three. It will not work in slot four, the uppermost slot, because of its size.

Another reviewer mentions using this card as well as the old card in his computer. (As an aside, there is no "Late 2008" Mac Pro. The 3,1 was the only model released in 2008 and it was produced until March 2009.) This is not recommended as there will be no performance increase as the cards will not work together. In fact, the displays on the old card will have lower graphics performance than the displays on the new card as the cards work independently and do not share workload. (You need two identical cards and something called Crossfire for the cards to work together. The Mac doesn't support Crossfire and, as stated earlier, it is not possible to run more than one of these cards in your computer at a time.)

For those of you with older Mac Pro's, there are reports that this card or the Radeon HD 5770 may work in the 2006 and 2007 models as well (the 1,1 and the 2,1 respectively).

In addition, during the course of my research I was linked to an article that discusses running this hardware and other cards in the 2008 Mac Pro. The article also gives some benchmarking information for those who may be interested. [...]
