I m going to buy a computer next week, and I want to ask my brothers some questions, come in!

I recently DIY a computer myself.,The gap between them is simply minimal.,It's not necessary for us rookies,**That is, the gap of dozens of fast money,The main frequency is more than a few tenths of a few,Can you feel it? It's not interesting,Hard disk,Western Digital 640GB 16MB is already quite good,I use it myself320G16M cache of 300 yuan,There's no need to add icing on the cake,Of course, if you want to keep up with the trend the most,32M is faster than 16M, that's for sure,When you reinstall the system,It may take 5 minutes to read the data,You may only need 4 minutes,If the general household is not necessary,Exceptions for other purposes,Now computer accessories are updated faster,**It's also a day a same, 16m's is still the mainstream,32m**It's more expensive,Just like a quad-core processing, it's a thousand fast ones,It will still come down in the future,Power supply,The most important thing is a brand,Secondly, the power is at least 300More than Huntkey。 Xingu

The Great Wall is currently the best 3 brands, the performance is good, the optical drive, it doesn't matter if we are a rookie, just reinstall the system.

1.My personal opinion is for 250u, 2The blue disk focuses on energy saving, and if you don't play games, you don't need to change the black disk.

3.Let's use Huntkey's 220W power supply, which is more reliable.

4.After all, people are the leaders of the optical storage industry.

AMD Athlon™ II X2 245 Parameters:

Number of cores: Dual cores; Thermal design power consumption: 65W; Core Voltage (V):; Fabrication: 45 nm;

CPU frequency.

Frequency 2900MHz

Frequency doubling (double) external frequency 200MHz

CPU caching.

L1 cache 128KB

L2 cache 2MB

AMD Athlonon II X2 250 Parameters:

Number of cores: Dual cores;

Thermal design power consumption 65W core voltage (V) Fabrication process 45nm CPU frequency.

Frequency 3000MHz

Octave (times) 15

External frequency: 200MHz

CPU caching.

L1 cache 128KB

L2 cache 2MB

250 is just a high frequency, and it's not worth 35 yuan more, so it's better to choose 245.

Choose a 32MB cache for the hard disk, which is fast.

It is best to consider buying a power supply with stable output current and high power factor, as unstable output current will reduce the life of the motherboard. If the grid voltage is unstable, you have to buy a wide power supply, so as not to turn off the computer if the voltage fluctuates casually.

The maximum read speed of the ***-RAM of the Pioneer ***-230D is higher than that of LG DH16NS20, the reading speed is fast, and the noise is small.

The hard disk wants to send things to the serial port and the parallel port to get stuck with you.

1.If you only play some online games with low configuration requirements, there is not much difference between a dual graphics card and a single graphics card. If you are playing large single-player games such as Call of Duty, the dual graphics card crossfire performance is better.

Dual graphics technology can double the graphics processing power, and in practical applications, except for a few tests, the graphics performance in real games can only be improved by 30%-70%, and in some cases even no performance improvement at all, and there are not too many games that can support SLI well. Of course, with the improvement of the driver, these problems should be gradually resolved.

2.Launched in October 2011 for high-end enthusiast users, the Dozer is a completely redesigned AMD architecture that replaces the Phenom II series processors with DDR3-1866 native memory support, XOP instruction set, modular design and many other new features.

The bulldozer is better than the A8 Both the architecture and the frequency doubling are better than the A8 and the i5 i7 is definitely not good compared to the i5 The third generation of the i5 is more suitable (according to your ** words).

3.Lenovo Y570 is good, **550 or so (Y580 is better, it's just**6800 or so).

1. The dual graphics card can switch between high efficiency and energy saving, saving the battery. The disadvantage is that you can only choose W7And discrete graphics cards are just so different.

2. In terms of processors, the i platform beats AMD, and I personally recommend choosing the i platform.

Pay attention to check the specific parameters of the graphics card and select the memory type DDR5. The 650m high-end configuration is good.

Dual graphics cards are integrated graphics cards plus independent graphics cards, play games directly buy a computer with a separate graphics card, the CPU generally looks at GHz, and playing large games is generally left and right.

It is recommended to buy an assembly machine directly.

In terms of graphics card, it doesn't need to be expensive, 800 yuan is enough for the graphics card.

Support domestic production!

Go to Suning Gome to buy it, because some special machines are only sold in places like Suning Five-Star, and they are not expensive. Fujitsu notebook l0ah531acsaj20100 4999 yuan. Lenovo Notebook Ideapady 471A 4800

I use Lenovo Y471A, the main game video and audio, dual graphics card i5CPU, not bad. Lenovo's brand is also very good, I bought it in Suning, and I bought it with peace of mind, at least it won't be like a computer city, taking low-profile ones to fool customers. Remember to configure it when you buy it.

Dell Inspiron15R is very good,Large screen,It's a game video book,It is recommended to go to the computer city to buy,It's expensive in the store,Model replacement is slow,After-sales are the same。
