If you buy a PC or a laptop and you wonder what CPU to buy for it, consider first for what do you buy that computer or CPU, if you use it more for editing text, excel, power point, all MS-Office suite or Open Office, web surfing ,chating, watching movies,you can buy an entry level class processor if you want to see HD movies, editing photos, playing games but not the most demanding ones( video card is essential if you buy a high range one is OK if not NO HIGH - DEMANDING GAMES)
you can buy without worrying processors from the middle –range.
If you want to play the latest games, multitasking, overclocking freak, and pretty much everything you want the hight end line is for you:p
Processor, together with the motherboard, video card and memory are the basic components of a computer. And, of course, these are the most difficult choice.Because they are so much and some so close in price that ultimately the decision willbe influenced by affinity for a particular manufacturer. In terms of processors, the situation is somewhat unclear, those who want a more powerful but still at a low price will opt for AMD and those who simply want performance without looking at the costs will opt for Intel.
Naturally, each manufacturer has its share of advantages. AMD has a lower temperature and the integrated memory controller works well with RAM, and Intel is doing much better in rendering, encoding, editing, not to mention the overclocking. But to see how the processors are divided into categories depending on performance because they will be used only in certain areas.
For the entry-level we have the AMD Sempron LE / Athlon X2 and Intel's model Celeron/E3xxx, E5xxx and with 2gigs of ram are excellent processors for use in the office, which does notrequire large computing power.
Do not try to use in gaming systems because you will be disappointed, and the overclocking results are not good at all.
In the middle we find the dual-core and triple-core AMD Athlon2 X3 and Phenom2 X3 and dual,core models of Intel E6xxx Series, G6950, E7500/7600, i3 andE8300/8400 Core. Already here we can talk about overclocking, 3DMark scores, multitasking, editing / encoding video and so on. They are powerful processors, able to handle any application. But those who want performance without limits do not forget that there's another category of processors.
In this category with 4 gigs of ram (DDR2/DDR3) and video card as the HIS ATI Radeon HD 5670 IceQ 1GB GDDR5,128 bit, can run even the most demanding games of the day in reasonable conditions.
High-end. In this category are quad-core processors and six-core products for both AMD and Intel. There is no secret the name of the AMD Phenom2 X4,AMD Phenom2 X6 or Q9xxx,Intel Core i7 and some i5 processors from Intel. If you want maximum performance here you will find all that you need.Overclocking, rendering and editing time increasingly smaller, multitasking, GAMING ,anything you imagine can be found on these processors. But performance has its price.
