How do you see your computer configuration in the end is good or not?

Many friends in the purchase of computers are very tangled, in the end what kind of computer is worth buying, in the end what kind of computer is really valuable, really have cost-effective, below, small series on this issue to do a commentary, in the end how to see the win7 system Computer configuration.

1. What should we say about dual-core, single-core and quad-core? In the current mainstream form, most computers stay on the dual core, so that the single-core computer people do not buy, not much significance, if the configuration requirements are relatively high, buy four nuclear hao.

2. From the production point of view, the current nanotechnology has become popular, 45 nm technology in the same area of the chip placed more transistors, but also make the computer better performance. Simply put, the current nanotechnology includes 45 nm, 65 nm, 90 nm, the present 45 nm technology is the mainstream, 90 is already rare.

3.CPU in the computer to dominate the speed of the computer running, CPU dependence on level two cache is relatively large, because the level two cache is mainly used to store data, so this factor for the computer configuration is also extremely important. In the current mainstream, the Internet CPU will be better.

4, you should also have heard of integrated graphics, independent graphics card it? When buying a computer, generally will also introduce the factors, generally speaking, the status of the video card is similar to the CPU, the market better graphics card manufacturers mainly have Nvidia and ATI two, is a good. Generally speaking, the computer configuration requirements can be considered integrated graphics card, home more practical, but if you need to install more large-scale software, the small part is recommended to use a discrete graphics card.
