Intel Pentium Extreme Edition 840
 

In a multithreaded environment, the CPU demonstrated some excellent
performance, besting the 3.73 Extreme Edition which has a 266FSB and over
500MHz clock speed advantage. Image and video editing are really the 840's
forté as we've seen results that are truly amazing. We didn't publish the
results, but DVD Shrink was remarkably quicker with the Extreme Edition
840, taking half the time the 3.73 XE did to shrink Revolutions, and this
was during our multitasking tests.
