[AG-TECH] inquiry on the hardware specs...

[Jay Beavers]

I've found HyperThreading to be useful in boosting A/V performance, but
not perhaps to the HyperClaims amount of 25-30%.  I'm seeing more like a
10-15% boost in overall performance.  However, I'm using a video
compressor and A/V application which is also multithreaded, so you
mileage may vary.

The hyperthreading note below is intriguing - does it REALLY give us a 
boost by simulating two extra processors?  Any other experience here?
