Breathes New Life Into My 2009 Mac Pro (4,1)
By S. Jacobs
I have a dual-quad 2.26ghz Mac Pro and was using it with the 4870 card from Apple. It's a great box, even as it's approaching 4 years since I bought it, but the video capabilities of the 4870 were showing their age BADLY.Like many Mac Pro users, we're on pins and needles waiting for Apple's newest system. Since it looks like it's going to be a while still, I wanted to bump the older system up and move the new card to the new Mac Pro when it comes.My impressions of the 7950:The card is a very nice looking white, full-length card, but is slightly shorter than the 4870 card it replaced. Packaging is on a par with what you'd expect with a commercial product. It came with a well-written users manual, a PC driver disc, a Mac OS X disc, two power cables (the card draws too much power to be powered only from the PCIe bus) and some random bits of paper.Installation was very easy. Be sure to read the manual, because it will ask you to install the driver software FIRST. It's very simple, launch the correct installer for your OS (either Lion or Mountain Lion), reboot the system. After reboot, I shut the system down, removed the power cable from the back of the system, cracked the case, removed both power cables from my 4870, removed the card retention device, slide out the old card, blow out any dust, install the new card, replace the card retention device, reattach the internal power cables (or if you're upgrading from the stock card, install the supplied power cables in the sockets inside the system and attach them to the card, making sure they're firmly attached and click into place). After that, close the case, reattach the main power cable and power the system up.The system worked without any changes or reconfiguration. I noticed immediately that showing the open windows and desktop in Expose were greatly faster than before. I brought up some OpenGL apps and they were spectacular. I was able to go to the highest detail level on games like SecondLife and everything was very snappy.I've not noticed any increase in background noise moving from the 4870 to the 7950, but I also have 50+ year old ears.I'm very happy with the 7950 card and consider it money well spent breathing new life into an aging system.

Good But Know A Couple Of Things
By ibscas
Great card, works for my purpose but has a few things you should be aware of...First, it takes TWO PCIe power cables, meaning if you are like me and have more than a couple monitors (I have 4) then you will have to get a 6 pin PCIe power splitter to make more than one card work.Second, since I did not yet have the splitter I tried this on 4 monitors, then three then just two of my Mac 27" 2012 monitors and it pixilated like crazy, it could not handle the resolution of two high end monitors, let alone 4. It WILL drive 4 but if you do anything graphical forget about it, if you are just surfing it might be fine.The fan is quite loud when running on a load, but it is very good about powering down properly as your graphic needs on that card decrease, I was very pleased with that and the heavy duty construction of the card. I think this is the best card on the market right now for Macs, far better than the NVidia junk that is out there that I have now gone through four of them (and at $400 each that's not cheap to do).

By Richard Mead
After installing the card, I got no improvement in performance - until I turned the settings of the test programs and games up to maximum! I'm now able to use the highest settings for all my games, both in MacOS and Windows, with no difficulties and great performance! Easy enough to install, my only regret is that it is so small that it does not lock in place like previous cards.
