Unlike laptops, desktop computers don't run on batteries, so there's no such thing as too much processing power. Regardless of what it will be used for, more GHz short for gigahertz means a faster and more responsive computer and, by extension, a happier user. Since multicore processors appeared on the scene, raw GHz hasn't meant as much as it once did.
Actual value is Clock speed, a. Processor speed is often played up to be the major factor in a computer's overall performance.
In rare cases this is true, but an average user rarely uses percent of his Central Processing Unit's power. Things like encoding video or encrypting files, or anything that computes large, complex, numbers requires a lot of processor power. Most users spend most of their time typing, reading email or viewing web pages.
During this time, the computer's CPU is probably hovering around 1 or 2 percent of it's total speed. Startup time is probably the only time the CPU is under stress, and even then it's often limited due to the hard drive speed.
It is the driving force in the power the processor has all other things being equal. Higher MHZ chips use more power and produce more heat. It stores data right before and after it is processed. This is what makes a Pentium 3 or 4 chip different than a celeron chip x86 is the architecture type of all Windows based computers.
All processors sold today for computers running the Windows OS operating system are 32 bit, meaning they process 32 bits of information each clock cycle a 1GHZ chip does 1 billion clock cycles per second.
Not all CPU's are x For example Apple computers use Motorola's chip design called PowerPC, which comes in both 64 and bit flavors. This is one reason apple computers can outpreform high-end PC's, despite their lower processor speeds. Currently Intel and AMD are developing 64 bit x86 chips.
The disadvantage of higher bit architecture is that one needs to make changes to any software that one may want to work with on the new design; this is one reason Mac software will not run without specialized software on PC's, and visa-versa.
