Just wondering how well the T2X00 Core Duo processors stack up against the rest of the products out there today? I'm just confused between an Intel Core Duo running at 1.83 - 2.16 ghz, while there are other dual core processors from Intel running at approximately 3.0 ghz or even greater. I'm interested at the iMac, but was just wondering why the clock speed is considerably slower than all the other chips out there, while everything out now is dual core and comes from the same company? For example The Core Duo T2600 at 2.16 ghz sells for $444.99 at www.newegg.com The Intel Pentium D 950 Dual Core at 3.40 ghz sells for 339.99 at www.newegg.com I guess I'm just not up to date with all this processor stuff. Any help would be gladly appreciated.
