I've never actually bothered to look. All I know is that I have never had
any stuttering, pausing, or any other performance based glitches at any
speed, despite whatever else the box is doing in the background. If I get a
chance, I'll do some quick benchmarks and mail the results to you.

I know it's been mentioned before, but this is a situation where it would
really be cool to have a standard, myth-centric script that can gather
hardware/software specs, and play back a reference clip in various manners
and record benchmarks that a person can post to their wiki user page for
easy comparison. Maybe I can throw something together to get the idea
started. It wouldnt be hard just to cat some config info and hardware specs
into a text file at the very least.
