| By the way, can someone tell me the difference with Duo Core and Duo 2 Core! |
The "Core Duo" processor is the dual core processor that has been in use in notebook computers for about 6 - 8 months (there is also a Pentium D and Celeron D dual core processors for desktops).
The "Core2 Duo" is the new processor which was code-named "Conroe" for the desktop processor, and the "Merom" for the notebook. These processors are reported to be about 40% faster than the Duo Core at about 40% more power efficiency.
The E6600 (2.4 Ghz), and the E6700 (2.66 Ghz) have a 4MB L2 cache which provides a lot of fast memory for specialized use in multi-tasking - in other words, the chips response times are improved greatly.
The E6300 (1.86 Ghz), and the E6400 (2.13 Ghz) both have the 2MB L2 cache which the same as the "Core Duo" cache.
The new Core2 Duo chips run at 1066 Mhz front side bus speeds, which allows very fast memory and video communications. By comparison, the "Core Duo" chips run at 667 Mhz front side bus speed - fast for the notebook computer.
Dell, HP, and a few other manufacturers have already started producing machines with these new processors, so if you are looking for the top of the line stuff - this is the way to go (as far as Intel goes).
Since I run Intel processors and MoBo's, I will leave the AMD info to more competent sources here.
