Intel Celeron and Pentium are the lesser processors and can better be avoided.
Intel Core i3, i5 en i7 are the stronger processors. These processors are buildup by integrating multiple individual processors named core's. The i3 has a maximum of 2 core's and is cheaper but also weaker than the i5 which has a maximum of 4 core's and cheaper but also weaker than the i7 which has a maximum of 6 core's
De Intel i3, i5 en i7 come in two packages (form factors). The Sandy Bridge LGA 1155 is more expensive but also much faster than the LGA 1156. The Sandy Bridge also has an integrated video card which the others dont. The newest powerhouse is the LGA 1366 for i7 processors. It is very expensive.
The processor is often meassured in
frequency and cache. The i7 Sandy Bridge has a frequency of 2.7 GHz and a
cache of +/- 8 MB in comparison with the i3 of 1.4 GHz and a cache of 1MB.

When purchasing laptops online, be aware of the conditions of the products your buying. Below you will find an Lenovo's explanation of the different conditions in which laptops can be purchased.

Laptops almost exclusively uses the client versions. Mentioning only the versions that are widely in use window Client versions are split into Windows XP SP3, Windows Vista, and Windows 7. These systems are again split in X86 which is 32 bit and X64 which is a 64 bit system. Although the 64 bit system obviously runs faster, it still has a lot of compatibility problems with applications, printers and other devices. At this time I recommend users to avoid it, unless they know exactly what they will use it for and with and are sure they have the necessary drivers.
The client versions are seperated in a Home version, a professional version and an ultimate version.
The home version has all option that we normally need except the ability to access a Domain. A Domain is a centrally managed network which you will usually find in an organization or bussiness.
