I used to all about these things but ive been off the scene for a while. What i wanted to know was what was the best dual core chip for desktops and the bet one for laptops? I.e. whats the difference between core duo and core 2 duo. Also how can you tell what ghz an amd processor is when all it has for a name is a random code. + which is better at the moment intel or amd -or is that by the by. Thanks for the help.
