If this were boxing, the Intel Core 2 Duo E6700 would be Lennox Lewis, the Athlon 64 FX-62 Bernard Hopkins and the Intel Presler E.E 965 Ricky Hatton. They all punch their weight, but some punch a lot heavier than others.
There's no real need for a summary. The benchmarks tell all. Intel's Conroe simply outmuscles every currently available CPU. Would you buy an AMD Athlon 64 FX-62 now? AMD must be thinking that K8-L can't come soon enough.
A little bird also tells us that the Intel Core 2 Duo Extreme Edition may well debut with a 3GHz clockspeed. Just imagine that. Gentlemen and ladies, start your salivating.
