That would be fine, if I didn't get horrible NVP prebuffering stuttering
(1/sec) on HD content with the power management messing with the clock
speed. I never noticed with the 4600 but I always ran that one at full
throttle with 2 SETI at home tasks so power management never clocked it down.
Then I went all green and got the lower-power handpicked chip, turned off
the SETI tasks, and it doesn't work right at the most green setting. I
compromised by having SETI only run half the day (when I might want to be
watching TV).

FWIW, my Kill-a-watt saw a 10W system difference between the 4600 and BE2350
at idle (110W vs 100W), 20W at full load (170W vs 150W).
