I'd really love to have the hyper threading in the i7 but it just puts out too much heat. I'd happily pay the same price for a 3.4GHz i7 instead. Is it possible to underclock the 4GHz i7 in a reliable way? As I understand it this processor is unlocked. But how would I go about it? I've never been into the overclocking scene so I'm a total newbie.
