Intensity and HDV

I just bought a Intensity Pro video card for my 2x2.66 dual core Intel Mac OS 10.4.11 (Tiger) I have 3 X 500 GB HD raid 0 for video capture, 4 GB of Ram and use a Sony GV-HD700 as my deck and a Sony Z1U camera. I have been capturing HDV through firewire but now both the GV-HD700 deck and the Intensity card have HDMI connection. So I’m wondering if I should capture using it.
I originally got the card so I could get monitor out through HDMI, also because my clients usually ask me to output to a BETACAM SP, but basically because you can’t beat uncompressed SD and HD output for under than 400 bucks.
I know that if I capture trough HDMI my files will be a lot bigger, but will I have a better quality? What will my benefits be? If I cant afford uncompressed due to file size what other compressor should I use? I know I can use DVCPRO HD, but if I’m capturing Image at 4.2.0 why upgrade the image to a 4.2.2? or perhaps there is recompression when going into the Mac through the firewire and will have a much better image quality when capturing through HDMI? And last but not least is my setup enough and how will I be able to control the deck if I’m not connected using firewire? Or maby I should stick with firewire.

I know that’s a lot but I have this going around in my head for the last week and the web does not have an answer for such a specific setup.

I’ll be installing the video card next week when I finish the project I’m working on at the moment, I don’t what to mess up my computer in the middle of a job. But would very much appreciate to know all the facts before I start doing tests with it.

Thanks.
