The E6750 ($195 via Newegg Promo Code: EMC911CPU03) is manufactured on a 65nm fab process and runs at a stock clock speed of 2.66GHz. Although its bus speed has jumped from 1066MHz to 1333MHz, its thermal design power (TDP) rating is unchanged at 65W. The E6750 is even compatible with LGA775-style sockets, though it does require a motherboard that supports its faster bus frequency. [...] At this speed, the E6750 is the fastest dual-core processor we've ever seen.
