Is there an advantage in using a FW 800 PCI-E card over a FW PCI card ? Also I have read about 32 bit / 64 bit cards and buses. Does this relate with the DAW software being 64 bit ? Or is it just the compatibility with the operating system ? therefore having no affect on audio software operation ? I have just finished a W7 Cubase build and have a Lacie FW 800 PCI card laying around that I could use. I do know that 800 is backwards compat to 400.
