I am quite happy with it doing -STABLE buildword under hour-and-a-half and re-encoding DVD movies at ~250fps.

Just out of curiosity -- what are you using to visualize this?

There are opinions whether doing C3 on one core (as I do) gains you anything, but, I believe, there is general consensus about C2. In my case, it seems to improve both battery life and heat dissipation. > I think I have one higher level, 2000/something at the start. I'll > look tonight > or tomorrow. That, likely means 2GHz processor, and AFAICR 64-bit capable to boot. -- Alexandre "Sunny" Kovalenko (Олександр Коваленко)
