MP3 Encoding:

We used LAME MT for our audio encoding test - it's the multi-threaded version of the popular LAME MP3 encoder. We ran tests with both Intel's and Microsoft's compilers - naturally, the Intel compiler resulted in some performance increases on Intel's processors. We converted all 18 tracks from Moby's Play album to a 192kbps variable bit-rate MP3.

Windows Media Encoder x64 Edition 9

Windows Media Encoder x64 Edition 9 comes as a free extra for 64-bit versions of Microsoft Windows. We encoded a 1440x880 Taxi 3 h264 trailer into 1280x720p VBR Windows Media Video file with CBR six channel audio in two passes, measuring the length of time it took for both.

And.. yes, more of what we expected - it doesn't matter what codec or software you use, this CPU works and it works damn fast.
