NL: Review Block - Sound Cards

We haven't reviewed any sound cards in quite awhile, in fact the last one we reviewed was a Hercules part that we still use here in the Ninjalane Labs every once in awhile.

- Diamond XtremeSound - 5.1/16 bit Sound Card Review @ OCC
- Auzentech X-Fi Prelude Sound Card @ APH Networks
- Diamond Xtreme Sound 5.1 Review @ GamePyre

Eventually we'll need to get a hold of that Auzentech card.
