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.
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: Put this in my 2008 Mac Pro. Works great with Mavericks. Makes gaming fly and large Photoshop files scroll and refresh instantly. While this is a double wide PCIe card, it "happens" that Apple made the first (video) 16x slot a double wide as well so the card does not cover the second 16x slot where...
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.
