I thought that I would post this here because this is the first card I have found that does above 64bit/33mhz.

Why is that important?
-Because for one, if you are using one of the run-of-the-mill 64/33 cards on a pci-x bus it will change the entire pci-X controller rate down to 64/33. That means that any other high speed storage you have attached automatically gets it's bandwidth to main memory, cpu, or anywhere else cut in half. I'm not sure if this happens on the new G5 workstations but it does on all pci-x interfaces on the x86 side of things so it's a safe bet that it will. (With a G5 you have a pci-x 64/133 interface which puts your arragete bandwidth above 1GB/s... 64/33 puts you at 266MB/s so you can see you'll lose a ton of bandwidth using a regular card if your bridge can not support dynamic connections at different speeds.)
-Second, this card has 4 controller chips for four interfaces which gives the 4 fw800 interfaces their own private channels instead of the regular cards that share one channel for 2-4 firewire ports. That means more effective bandwidth and less chances of maxing out the card's throughput when tramsfering HD, DV, or SD. (HD can be upwards of 150MB/s depending on the codec)
This is truely a professional firewire solution... one thing to note, however, is that this card needs at least a 64/66 pci-x connection which means you'll need to use it with a G5 that has pci-x interface of at least 64/66 and not the G4 pci interfaces that run at 64/33.
