Short term though the PCI express leaves me with redundant SATA and Blackmagic cards. Makes upgrading a far more expensive exercise than I would like.

true, but by the time you need to upgrade your machine to a new one, you would probably want to get a hi-def SDI card anyways ( assuming you dont have one now) and SATA cards are really not that expensive.
Besides, who knows when you will really need to upgrade to new machines? It is still not known what kind of performance increases these will give you. The increase might not be very noticeable in using catalyst for a normal show. I'm sure once you start looking at high def, this will be a big increase, and by the time you need to go high-def, you will probably need a whole new machine anyways, then you can keep your current setup for doing standard def.

hopefully nVidia/ATI wont mean anything.
but i dont have any computer to test with.
i rewrote to be card agnostic some time ago - though this isnt in v3.3
the new macs support multiple video cards - which may open the way to more than 2 outputs. dont know yet.
and the shift to pci-express- may open the way to a usable xserve in the future.
at the moment they dont have any agp graphics card support.

pci-express is totally different from pci-x or pci.
not any kindof compatibility.
it would have been less confusing to have given it a new name.
we are told atto with have a pci-express ul5d in november.
the apple hardware technote is at
http://images.apple.com/powermac/pdf...erMacG5_TO.pdf
i believe we have information from blackmagic that versions of all their cards will be available with pci-express shortly.
And miglia is a possibility too. though not confirmed
Atto will release a new PCIe SCSI card in early November - the UL5D. This is a dual channel card. Decklink have already released the Extreme as a PCIe card, with the others to follow.
Aurora and Miglia have got back to me but haven't given specific release dates on products.

Atto will also release the first PCIe Fibre Channel card.
The big thing, guys, is multiple graphics cards. The PCIe architecture will support multiple nVidia cards - two FX4500's or 7800's and four 6600's.
SDI is a double-edged sword. It would be cool to have the option of outputing to SDI/ HD SDI without having to go through a scan converter.
Richard and I will report our findings when we get our new Macs.

performance in catalyst will depend on things people havent tested yet.
it will depend on whether quicktime can spread the codec image decoding effectively across multiple cpus, and whether they have got disc access to be multi-threaded.
up to now disc access across the entire system has been single threaded - which means only one discs is ever accessed at a time.
so having 2 or more discs doesnt make things any quicker - it still seemed to have to wait for the slowest one...
Catalyst can take advantage of multi-cpus, it is multi-threaded.
but everything important depends on what apple has done.
