Firewire 800MHz vs 400MHz?

I've been reading a bit about Firewire 800MHz.
Will it make a difference when capturing from MiniDV camera? I can't see
how when it's capturing in real time and I don't have any problems with
dropped frames.
I'm assuming I'll need an 800MHz firewire card and maybe a new cable which
supports 800MHz but must the motherboard also support this standard or just
the card?
Related question. Thinking of buying an external SATA/Firewire/USB2 hard
drive, will it make much difference in rendering speed for video? I also
have the option to add internal SATA drive, would that be better?
Currently using a 160GB/7200RPM/8MB cache on Secondary IDE for working space
and storage.

The operating cycle is dictated by the slower port.
If you output at 400megahertz cycle, it stays as such.
If you install a 800Mhz card, it cannot "up-cycle", if
the bandwidth is being transferred at 400Mhz, then
that is what it is captured at. Also, if transferring
footage back to DV cam from a 800Mhz output,
The DV cam will only capture at it's predefined
operating cycle of 400Mhz, you cannot upgrade a
DV cam cycle.
But there is no detrimental effect neither.
400Mhz will function just fine with 800Mhz,
but at 400Mhz.
 
Thanks for the reply, after reading a bit more have decided to forget about
the 800MHz Firewire for now and go for the fast HDD since I think that may
help make video rendering a bit faster.
I find this painfully slow even though I have a reasonably fast PC with
Athlon 64 3200 and 1GB RAM.
