(Doc title is actually "Java for Mac OS X 10.5 Update 1 adds support for Java SE 6".
Note also that doc says "This release is for 64-bit Intel-based Macs only and cannot run on PowerPC-based or 32-bit Intel-based Macs".-Mike)

System requirements: Mac OS X 10.5.2 or later
(they later updated the D/L doc to also note)
64-bit Intel-based Macintosh"

If you find this fixes or breaks anything, let me know the details.

• 512MB of DDR4 vram (256-bit wide I assume)
• Supports 1st gen and 2008 Mac Pros
• Dual boot Windows/OS X (OS X 10.5.2 or later)
• Crossfire supported when booted to Windows
• Mac OS perf. said to be similar to Mac 8800GT (but remains to be seen)

With the Mac 8800GT priced at $279, IMHO the Mac/PC 3870 will have to be priced at or below that card. (And every day that passes means more potential lost Mac Pro owner sales now that there's versions of the Mac 8800GT for both 1st Gen and 2008 Mac Pros.) Again no official ATI info on this mac/pc model currently, although they have (PC/windows focused) pages on the ATI Radeon HD 3000 series.

"We are working on Leopard drivers for Revolution 5.1 and they are currently in final testing. We hope to launch them shortly but I don't have a date yet. Sorry I can't be more specific."

I also wrote to ask about driver updates for the Revolution 7.1 audio card.
(There's previous pages here with owner reports on the Revolution 5.1 and Revolution 7.1 PCI audio cards.)

If you've upgraded the CPU on your Mac, send a review with your experience (performance/stability/installation, etc.), Mac Model/Upgrade brand info and overall rating (1= worst to 10=best). If you can, please run some tests with the original CPU vs the upgrade (for example time some tests with your favorite app, game, etc. - see full reviews here for example tests with common apps/games/benchmarks.)
