Microsoft, together with Intel, AMD, ATI and Nvidia, released the basic recommended configuration requirements for Windows Vista certified PCs. Many common hardware appears in the list, so users who buy computers in recent years can be reassured. The recommended configuration requirements are as follows (including but not limited to):

If you spend a small amount of money on a PC and you end up with just the text, you're likely to be disappointed. Similarly, if you are going to assemble a gaming PC and save money on the CPU, it may also be a bad decision.
Our goal is to use a limited budget to build a best performing PC. Don't worry, there are a lot of CPUs on the market to choose from, from the most popular chipmaker AMD and Intel, which focus on different areas. In addition to the CPU, you have to consider other PC compone
It doesn't matter if I want to engage you, but if you are a little overdo, sell your money with someone else's manuscript, and decorate yourself with someone else's technology. I have to remind you that your superiority is based on others' contributions.
