currently have a e7300 2.66ghz core 2 duo running in a pc, was given a free e6700 pentium dual core 3.2ghz. was wondering which one is better? is the 3.2ghz much faster? core 2 duo has 3mb L2 cache vs the pentium dual core 2mb L2 cache. i know the e6700 supports virtualization while the e7300 doesn't.
