Nice system. You might also want to get a combo Blu-Ray/HD-DVD drive in there. HD-DVDs are soon to be in the <$10 bin in wal-mart, so its a cheap way to enjoy HD Movies

Also, given the cost, did you look into the dual quad intel board? I bet 4 more cores would help your DAW out immensely, and give even more headroom for 5boxing wow (one core per instance, and 3 for sound )

The FB-Dimms will kill you even more on cost, but if you are already looking at dual 9800gx2s, it doesn't seem like a few hundred dollars scare you. You could even just put a single quad in there and see how it goes, then add another later, or upgrade both when the 6-8 core cpus come out.
