Not sure how pleased the good people at Intel will be about this, but Alienware just broke the 4GHz barrier by deliberately overclocking the 3.6GHz processor in their new Area-51 ALX gaming desktop and installing a special liquid-cooling system to keep the whole thing from melting down. And not surprisingly it'll cost you at least 4 G's if you want to get your hands on 4GHz.
