What people are missing in AMD vs. Intel power comparisons is where the RAM controller is. AMD's CPU wattages appear high for two reasons: The figure includes the RAM controller, and AMD's TDP figures are true maximum. Intel still have the RAM controller in the northbridge, and their TDP figures are actually lower than maximum wattage - kind of like "real life sustained maximum".
Anyhow. AMD's IGP solutions, the 690 and even more so the 780, are superior to Intel's by lightyears. They're cooler and cheaper on top of that ... so if you want a quiet, cheap and smooth surfbox, go with AMD.
