Default [Q] YSE5250 vs Arndale 5250

I'm stuck on deciding which of the two I should go with. Things I'm not sure about is the different sound boards and and network boards. Not sure which sound board is better but more importantly what modes the WiFi chipsets are capable of with regards to packet detection. Any advice is welcome. I'm sure there are questions I should be asking that I'm not even aware of.

My intended uses are for native compiling and network hardening / pen testing with a secondary use as a (semi) mobile DAC. Thanks in advance.

Well, Nvidia just made it a tougher choice, this is on Newegg for $192....
