They may be compatible but they do not have the require Mac boot ROMs. Apple sells the appropriate Radeon 5770 and 5780 cards through the Online Store.

You only have one double width 16x slot and no you don't want your (x1900 / OEM 7300GT) along too. Lack of EFI means black screen until it gets to login with PC card, and flashing is one route or buy one or check MACVIDCARDS on ebay has more options - not a lot to choose from, and $$ pricing.
But... what do you have now? why now the upgrade?

Thanks for the info, hatter,
I currently have the original 7300GT card but I was hoping for something a little zippier. I do a lot of graphics... big graphics... and the rewrite is slow. Also, I'd like to add at least one more monitor and maybe 2. I'm not sure about the 7300, but I know the ATI Radeon 5700 would let me do that...and even if the 7300 did, I'd be worried about performance.
This is the original MacPro Intel and I've been extremely impressed with how well it's kept up without the need to buy a new one... 6-1/2 years and counting! I have 14 gigs of ram, 3 drives (about 3 tb) internal and 3 drives (4 tb) external and I use it about 12 hrs day, everyday and often more. It's been a real workhorse! No complaints.

Thank you, Kappy... I couldn't find anything that mentioned NEEDING to buy an Apple-specific version, so thank you for clarifying that. ****... the plain vanilla PC version is SO much cheaper!

Yes, that's true. But there are some important drawbacks to the non-Apple versions. For one you have no ability to use startup options because the card doesn't provide a screen until after the computer starts up. That means no OPTION booting, no other boot commands working. All you see is a black screen until the Desktop appears.
If you have the knowledge and hardware then you can reflash the card's ROMs using an image from an Apple video card's boot ROM.
Nevertheless, as hatter points out you don't NEED the Apple version, but it makes life a lot easier. Then there is the argument that the 5770 is a better card than the 5700.

This series of cards do not show a picture under Mac OS X unless they have Apple firmware.
PC-cards flashed with Apple firmware do not show a picture until Mac OS X is completely initialized. That makes it very inconvenient to debug or boot from alternate drives.
These folks have a good deal if you are in the US, but NOT in NewYork:Mac Pro (Early 2009), Mac OS X (10.6.8), & Server, PPC, & AppleTalk Printers

Q: I have a big question, i see some test that the 5770 is almost equal to 5870 due to the mac pro hardware limitation but i didn't found any bench with a 570 or 680 to compare the perf?
Could you give me some advice?
A: I heard a rumor that such tests will soon be released by a known testing site.
