Intel Core 2 Duo E8500, E8400 and E8200
 

Just like the QX9650 and QX9770 the 45nm products are the ones to aim for if you're considering and Intel upgrade, however /unlike/ the Extreme Edition CPUs, the Wolfdales are *affordable*. In fact, every CPU featured was affordable, the only exception is the Q6700 at £311.
