don't get the Audigy 2 ZS. the DFI board has a good 7.1 sound card.
if you do want another sound card, you can actually get the Audigy 2 Value.
in fact the only difference between the Value and the ZS is the drivers.
there's instructions and download links for the drivers (they're quite large though)
I'd recommend downloading using a program that you can pause and resume downloads, like DAP, or Firefox
anyway, yay for Seagate. I have 3, and I love 'em.
Maxtors seem to be a mixed bag. some people have ones that last a long time, some people have them die very quickly. I'd recommend you don't risk it.
