the 800 series of intel cpus are all dual core. when you see the specs of them, for example 2.8GHz, that means that both of the cores operate at 2.8GHz. the 600 series has only one core, hence the lower price.
dual core and 64 bit are the future,

First of all I bought the new Intel 945 chipset on a Gigabyte board but I see a lot of people bying the 955 chipset on Asus boards. I didnt see a whole lot of difference between the two except 100$. Did I start out making a wrong choice. Im building this computer to be worth something in 2-3 years until I build another one.
Secondly I am confused about why cpu price varie so much but the specs say nothing different except .2 Ghz for example with the new LGA slot chips like the 800 series and 600 series the specs are identical (specs below) can someone tell me the difference between the 800 and 600 series and whether .2Ghz matters that much cant I overclock the difference. Thanks for your help
