[A must-read manual for newbies buying computers]

First let me state that I very, very much despise hidden posts, so any post I make will not be hidden. If it is a good post, am I afraid that no one will upvote it? I've got all the added essences. Children's shoes in the 7 forums read this article and think it's useful to you. Please give it a little thumbs up. If it doesn't work, don't blame me. At least I've read it myself and found it useful to me!

Many novices think that if they ask for a configuration sheet in Pacific Ocean, they will not be cheated by profiteers. This is a big mistake. I have worked in a computer city. Now I have summarized a few points and hope that fewer and fewer people will be cheated.
The first and most important thing to remember when entering a computer city is: what the merchant says is always wrong. Remember, it is always, always......For example, product A is better than product B, but product B is more profitable than product A. I guarantee that there will be 100 merchants who say it. Every merchant will recommend product B to you, without exception, why? Marx taught you N years ago: The purpose of capitalists is only profit, and they will use all means to get the maximum profit. What is out of stock? Or, oh, who wrote this configuration for you? Ah, I'm obviously trying to trick you. That's not good. I've been doing this for so many years. I believe in my professional opinions and so on, just to sell you my own profitable products. As for whether it is useful or not? That is not his problem. He only guarantees that it can be turned on in the computer city.
Second: Motherboards are not just based on solid capacitors and N-phase power supply. Many businesses deceive consumers with all-solid-state, five-phase and six-phase power supplies. Many novices will be fooled. I am also a graduate of electronics. Whether a motherboard is good or not, although the capacitance and power supply part have an impact on the motherboard, but not all, just like a car running fast does not require an engine with multiple cylinders~ But after remembering the first one, the second one will naturally not affect you.
Third: The video card does not just look at the video memory capacity. I believe there are many people who think that 512M video memory is better than 256M? That is wrong, the copycat 94GT I have seen 1G video memory, and it sold for more than 400. The 256M 4650 is definitely better than it in any situation, including what kind of benchmark games, what size and resolution monitor, why? Because it is 94GT, the core has determined its performance, and the video memory It's just an auxiliary part, especially for copycats. Many of them are low-end chips, such as 84, 85, 86, 94, 95, etc. added to 512 or even 1G or even larger to deceive novices. Of course, if you remember the first point, this one will not affect you.
Fourth: Try not to use the power supply that comes with the chassis. The chassis power supply is often the profit of the whole machine. The important components in front will be quoted at a relatively low price. Then use a copycat power supply, the kind with poor workmanship. It weighs less than a kilogram and has nothing except two capacitors. This kind of power supply is okay for general ultra-low-end configurations, such as Saiyang a few years ago. If you go up to dual-core, it's hard to say. The power supply is equivalent to the human stomach. Although it does not have the brain function like a CPU, if you eat poisonous food, the brain cannot survive. This is the role of the power supply in the computer. I have seen the motherboard and graphics card burn out together with the garbage power supply. Generally, dual-core + 96GT or 4830 and other levels use a Hangjia Chang. The city's 300W is totally fine, and the price is within 200. The chassis depends on personal preference, and it actually has little effect on heat dissipation. If you are really worried about heat dissipation, change to a CPU fan. This improvement will be greater than if you use a chassis worth thousands of dollars. The average chassis is within 100. Some brands of chassis + power supply also cost this price, but the quality is far inferior. I won't mention the specific brand. There are also some optical drive shell replacements, and the imported parallel imports are actually fakes, etc. Not to mention the shady story, which can't be taught in ten minutes, and it is not something that a novice can learn in an instant. Prepare several sets of configurations before going to the computer store. Generally, prepare three to four types of motherboards and graphics cards~ To avoid the phenomenon of genuine out-of-stock, prepare the configurations well, and remember the first point, which can greatly reduce your losses.
