I've actually had much better luck by having adequate power and I've overclocked somewhat. Also I changed the audio output so that it's not DTS, but just 2.0 stereo. From that, I can get almost no buffering. The power thing was killing me though, so it's working pretty well now. I'll post my overclocking information when I get back upstairs. It's pretty basic stuff that I found with a quick web search.
