Jave: the reason the highest CPU is 3c higher is because it actually is 3c higher. I've got an i7 that has three cores that are currently reading ~5-10c higher than the fourth and that core is almost always lower than the other three (it's low is 3c lower than the next lowest, and it's high is 2c lower than the next lowest). personally, I'd like to keep my computer running longer rather than cranking out one or two more points per day
