i7 920 uses 10W more than a C2Q 9450 which has full load power consumption of around 50W. Since games don't generally fully tax CPU, the full load system power consumption doesn't provide a necessarily accurate picture of the power usage while gaming.
K10 is bad because it neither had performance, performance/watt or power usage. Much the same way Prescott was bad.I couldnt care less about power consumption, just funny how K10 was so bad and now Nehalem is awesome![]()
