Got this card about a week ago. So far the results have been excellent. I downloaded the latest driver from the AMD website, rather than using the included CD, which is probably out of date.



I am running this on a Mac Pro 2008 (8 Core 2.8Ghz) computer in the first PCIx16 slot alongside the original AMD 2600XT which I have kept with no monitor plugged in, in case I need to see the boot screen.



The card requires two 6 pin molex connectors, so I purchased adaptors to go from the motherboard PCI power aux's to power the card.



As expected OSX 10.7.2 boots without a boot screen, only showing a brief grey apple screen followed by the username and password login. No flashing of the card Bios was required unlike previous AMD and NVIDIA cards. The gap between PC and Mac hardware support is closing.



Performance is great, mission control and hot corners(previously expose) are responsive and fast. Final Cut Pro detects the graphics card as a compatible device and does not show any warning screens unlike the stock AMD 2600XT. Steam games such as Half-Life 2, Serious Same BFE 3 all work at 1920x1200 resolution with over 30 frames per second with all settings maxed out and anti-aliasing enabled, which is not bad for a 4 year old mac. However........



Over on my hard-drive dedicated to Windows 7, the performance just gets better with direct x games working very well. I have been playing Modern Warfare 2 & 3 at 1920x1200 Max settings with 4X AA with over 50-60 FPS. Serious Sam BFE works even better with a clear 10-20 FPS increase over the Mac version. So far everything that has come out in the last 4 years has worked flawlessly on High to Enthusiast settings.



I hope to pick up another one and run crossfire when I decided to build a gaming PC in addition to the Mac Pro.



It is also worth noting that I have over-clocked the card to 930Mhz using the stock cooler and AMD catalyst software from the original 900Mhz. Temps go to about 60-70 degrees Celcius under 80% load, which is within the limits of the card. I may revert to the original clock if I want it to last longer and improve reliability in the longer term.



Shame the price just increased. This is slightly better than the 7950 that just came out, although has a higher TDP.
