intel atom,.,.,.,., core2duo

Well, it's different since their family (core family, pentium family, etc. something like that) If you ask my suggestion about which one should you use or buy then I would say intel core2duo. It faster and has more advantages than intel atom. However intel atom is cheaper and it has more duration on electric power. With Hi-k mental gate 45nm, it's become smaller and give more convenience. It use less electricity compared with core2duo so it'll less your expenses especially you have to buy more ram for the core 2 duo. However, it depends on prefernce of yourself, which one you prefer. Both of them has the same base. I think most of computer users want their computer to be fast. Anyway when you are going to surf internet, the internet connection is also one of major thing that provide you high speed connection.
