The asking price of desktop computer configuration is about 3800 yuan. urgent

The following configuration platforms are recommended for computer configuration of office drawing and games: Intel's CPU and a motherboard +HD graphics card. Reason: Intel's platform is suitable for many office softwares, all of which are applicable, with low main frequency and stable speed; A graphics card emphasizes the static picture quality and good drawing effect, so the following configuration is recommended!

On the Intel platform, there will be two channels in the memory bank in the future, which is faster and needs the same brand, model and frequency.

CPU Intel Core i3 540 (Distributed) 690

I3 dual-core 4-thread, 4MB triple buffer, large upgrade space.

CPU radiator: overclocking three Silver Knife (PA-99) 40

Or: Kyushu Fengshen West Tower 9 40

Motherboard: Elite H55H-M 480

Or: ASUS h55m-ge r2.0 480

The second line is fine. If they don't lose the first line and keep a low profile, they are matched by many world first-line brand machine manufacturers, such as Dell and Hewlett-Packard Lenovo.

Memory Yu Zhan or weigang 2GB DDR 3 13332G 140.

Excellent stability and compatibility ~ ~! ~, if you use Yingtai motherboard, you don't need to use Weigang memory. There may be compatibility issues. There are too many fakes in Kingston, so don't be greedy for cheap.

Hard disk western data 500g WD5000AAKS7200rpm 16M SATAII 270.

500G hard disk

Graphics card UNIKA, Wuji, 2hd5830dr51100 (price of New Egg Network City 1000, available).

Or: graphics card: sapphire HD5770 1G platinum edition 900.

Give full play to the platform performance, and the game performance is strong!

Strong performance, good workmanship materials and excellent temperature control! HD5770 is certainly better than GTS450, but not much better. And the price is higher than GTS450 150 or so. N rice said that GTS450 killed 5770, which is pure nonsense. NV people are not philanthropists. If GTS450 is really better than 5770, how can the price be lower ~ ~

GTS450 is similar to HD5750. HD5750 even sold to 650 GTS450, which had no purchase value at all. If only physical acceleration is considered, GTS450 is selected.

HD6000 has been on the market, and GTS450 will definitely drop below 800 soon.

The high-frequency GTS450 is as good as the Volkswagen HD5770.

The performance of GTS450 is only 5770 when the high frequency (overclocking) reaches 900MHz, but when it exceeds 900MHz, the full-load power consumption reaches more than 300 W. The default GTS450 can only be compared with 5750.

Power cooler main ares 500 watts rated 420 watts 270.

Rated 420W is enough.

Don't make do with video games. JS sent the worst and cheapest, and the game was not good at all.

The following is the 19 prompt:

1, the purpose of computer DIY is to build a computer with the highest cost performance, the strongest performance and full of personalized use, which is the fundamental purpose and spirit of DIY. So please tell the budget, purpose, use requirements and hardware requirements as accurately as possible, DIY will play its greatest advantage ~ ~! ~

2. Prepare two configuration sheets, one with the price for yourself, and the other without the price written on the blank sheet in the assembly workshop. Take the configuration sheet to the largest computer store in the computer city, find three stores, and let them calculate the money according to the configuration. They all have blank configuration tables. You write down the configuration list, not the price, and let them bid first. You have to cut lower, cut higher ~ ~! ~, CPU, motherboard, memory quotation is lower than my 40 yuan, so be careful, other parts may be surprisingly high, and there may be fakes in the store, so be careful ~ ~ (The gap may be slightly larger after May Day, November Day, New Year's Day and Spring Festival, and generally these four time points are price reduction adjustment periods);

3. It is best to find a listed motherboard, CPU, or graphics card agent to install, so as to ensure that the price of at least one accessory is the lowest. Otherwise, everything will be outsourced, and the price will be higher if each company earns you a little. Also, if you buy the goods they represent in their store, their enthusiasm will be high. Find the lowest one and buy it all;

4. When the accessories are brought here (unopened), you have the right to ask for inspection first, which is an industry rule requirement that you can confidently ask for, hehe! First of all, look at the packaging, integrity, whether there are signs of unpacking, fouling and so on. If there is, change it, because it may be repaired or fake! Then, carefully check the model and core parameters. There are different symbols or fewer symbols on the main model! Everything was ready when you left. Try not to leave the site during installation to avoid being replaced. It is best to go with two people, so that you can take care of it!

5. Memory and hard disk: Kingston has the most fakes in the memory market (90% of Kingston in use are fakes). If you buy a fake computer, the screen may be unstable. It is generally recommended to switch to Yu Zhan (with good stability) or Wei Gang. Shang Weigang's memory does not match with Yingtai's motherboard, and it is also unstable, hehe ~; Western Digital is generally recommended for hard disks. Seagate has a lot of quality problems recently, and the latest generation of 12 seems to be ok, but the overlord clause after sale is also unacceptable, which is almost equal to no after sale;

6. Power supply: it must be stated that it is rated power, which is easy to ignore. Many stores pretend to be Fengli, so we must make it clear that the goods will be confirmed after they are brought here; Also, if the voltage there is unstable or there is frequent sudden power failure, it is recommended to use UPS power supply, about 200-500. If there is a sudden power failure, it can maintain normal operation for 3-6 minutes, and it is very important to save data.

7, talk about monitors, Samsung, Philips and the like, which used to be really good! Now these brands are also OEM in Chinese mainland and Taiwan Province Province. You have bought domestic products for a long time, so there is no need to give others hundreds of brand fees! Domestic monitors can already compete with these brands, such as Great Wall, AOC TPV, Emerson, Acer, Hanshiqi and so on. , can be completely replaced, you can buy a bigger one at the same price!

8. Don't ask them to "recommend other accessories" for various reasons, such as out of stock ... They will generally suggest the brand they represent. Unless he represents a first-line or top-level second-line brand, the hardware model and price are reasonable, don't change or ignore him. In general, they recommend other parts because of their high profit and average performance, especially the four major parts (U, motherboard, graphics card and memory). Needless to say, CPU is Intel or AMD. Here we mainly talk about domestic motherboards and graphics cards: the first-line motherboards are Gigabyte, MSI, ASUS, and the second-line motherboards are Yingtai, Huaqing, Jiebao, Mei Jie, Elite, Spartak, Shuangmin, etc. Their performance and workmanship quality are almost the same as those of the first-line motherboards (whether they are genuine or not, they are very easy to use), but their popularity is low, but their prices are cheap and cost-effective. They are worth buying if the cost is tight. Graphics cards: First-line Sapphire, Dylan Hengjin, Asus, Gigabyte, MSI, Sotai, Jing Xun and other second-line graphics cards: colorful IGAME series high-end cards, Yingchi (screen and high temperature problems have not been well solved), MG (overall good) and so on are all popular graphics cards; Other qualities are average. Of course, the advantage of this board is that it is cheap. If the budget is not enough, I suggest you choose.

9. Different choices of motherboards. Needless to say, the A platform is equipped with a board, and the I platform is equipped with an I board. This is a common phenomenon of the same platform: AMD platform: if you choose a mid-range or above independent graphics card, it is recommended to choose the motherboards of independent chipsets such as 770 and 870, which will have better matching stability and compatibility and better performance; Don't choose motherboards with integrated graphics chip sets such as 880 and 785. I platform: integrated graphics motherboard G3 1, G4 1 and other chipsets; Independent chipset motherboards P3 1, P4 1, P43, P45, H55, P55, etc. Let's talk about the difference between 770 and 870, and the difference between H55 and P55: there is little difference between 770 and 870. 870 is a new motherboard chipset, which is new in 1, SATA3,2 and USB3.0. SATA 3 mainly doubles the transmission speed to 6Gbps, which is only a theoretical value. In fact, the speed of SATA interface sending information is 600 MB/s, and USB3 can really greatly improve the transmission speed, which is extremely rare for ordinary users when a group of disk arrays or multiple card readers are used together, and actually has no meaning; The difference between P55 and H55: 1, which supports graphics card crossfire and SLI, 2, RAID (in short, RAID is a technology that combines multiple independent hard disks (physical hard disks) in different ways to form a hard disk group (logical hard disk), thus providing higher storage performance and data backup than a single hard disk. )。 H55 motherboard provides a video output interface, and you don't need to buy a graphics card with I3 (some H55 motherboards consider independent display, and there is no output interface, so please note if you don't buy independent display); P55 is used for crossfire between two or more graphics cards, and P55 is also used for RAID of two or more hard disks. H55 is used for a graphics card and a hard disk, and H55 is also used for a hard disk without a graphics card. It is expected that you can choose to upgrade your computer in the future.

10, the choice of graphics card: general home Internet access and 2D games, then the integrated graphics card is completely acceptable; Large game consoles, A cards beginning with HD and N cards beginning with GT can be used. Of course, rice A says A is good, and rice N says N is good. At present, a large number of forums in China are full of n guns. Briefly talk about how N card overclocked, how stable and how strong it is, and compare it with the default of A card, which leads to the general view that N card is suitable for games and A card is suitable for movies and videos. This statement is wrong. Businessmen are very clever. If they can overclock, they will sell it to you at a higher model price, so they are not philanthropists. Overclocking is extremely risky, and it is not guaranteed if it is broken. Compared with HD5770 and GTS450 of the same grade, the 5770 is a little stronger, the games that GTS450 and 5770 can run and the games that GTS450 can't run have improved performance after overclocking, but the temperature is high, the noise is high, the stability is poor, the life is short, the power is greatly increased, and the power supply may not be enough, so it may be necessary to replace the power supply. Some people talk about drivers. A card driver used to be a weakness. Now the latest driver of A card has been perfected, which is not a problem. Personally, I am neither a meter nor an n meter, but practical rice (eat rice, eat), hehe! From the user's point of view, the pursuit is the continuity and shock of the picture. As mentioned above, at the same level, the continuity is basically the same. In terms of shock, it mainly refers to the high definition, high rendering details and bright picture. These are the advantages of A, so A card is generally recommended. Furthermore, professional graphics cards are generally recommended for professional drawing, professional modeling and drawing. Sapphire and Lee Tae are both available, and the price is relatively expensive. Game cards starting with GT and HD are not recommended, especially those starting with GT. HD is not a particularly professional 3D drawing, but it can also be considered. Drawing in the office is also a game, hehe ~

1 1, random gifts, are generally the products with the lowest performance and the cheapest price, such as cameras, keyboards and mice, headphones and speakers. Remember to ask them for money when it is tight;

12, the machine maintenance workshop is responsible for installing the system and common software, and installing them during installation. Remember to install Master Lu or other similar software. After installing the system, run Master Lu to check the hardware to see if the configuration list is consistent!

13. Ask for the invoice (legal person, +5% tax) or receipt (private person), and keep the packaging and warranty card (write the warranty date);

14, part of the price is ZOL, JD.COM Online Mall, Newegg, Yixun or Netneighbors, and the actual total purchase amount should not go up or down.

Exceeded 150 yuan. LZ can be purchased by comparison. (JD.COM price features: CPU is expensive; Some models of graphics cards are expensive and some models are cheap; Motherboard, chassis, power supply, monitor, CD-ROM drive, keyboard and mouse are cheap; Hard disk and memory are slightly more expensive; Second-line brand products are slightly more expensive. Net neighbors and new eggs are roughly the same)

15, the configuration list is basically complete, and the keyboard and mouse cover is still very important, especially for game machines, so there is not much difference in performance compared with the configuration list without keyboard and mouse cover;

16, the compatibility and stability of listed accessories are very good, and each accessory has no bottleneck, so it can give full play to its functions! Temperature control and noise are low-temperature and low-noise accessories. The quality is stable and durable. At the same time, choose accessories with large online evaluation and good defect-free bad evaluation to ensure the quality and use requirements of the whole machine to the maximum extent!

17, prices, listing prices are basically available everywhere, and the final total price fluctuates little. It is not the so-called channel price, delivery price and other prices that cannot be bought at all.

18, always remember that you are the customer and you are God! Any store's price increase and customer bullying, such as no accessories or replacement of accessories, can be exempted.

19, if you are interested, you can try to install it yourself, so you will have a very intuitive understanding of computer hardware! Each accessory has detailed installation instructions and charts, and the interface has a foolproof design. All you need is a Phillips screwdriver! The only trouble is wiring. You can ask a friend for help, or find a network manager who can install the machine. Paying 50 yuan can give you a good connection system, hehe!

If you have any questions, please leave a message. Happy installation ~ ~! ~
