I want to buy a computer graphics card and CPU and ask for help to explain!! Prawns in

You can't go wrong with IBM! The landlord is actually very important! A business has its image!

So! IBM is the boss of computers! Just like there is no GTX250 in the mobile phone, it is GTS250, in fact, GTS250 is the renamed version of 9800GTX+, the two use the same core - G92, with 128 stream processors and 64 texture units 256bit video memory bit width, and 9800GT has 112 stream processors 56 texture units and 256bit video memory bit width, in the case of the same frequency, the performance gap between the two is basically equivalent to the specification gap, that is, about 10%, However, it is possible for the overclocked version of the 9800GT to reach or even exceed the GTS250, so it depends on the specific product.

Nokia, the United States of the world!

You can go to Dell's ** custom one, configure yourself and tell them, what is the approximate performance, they will match it for you, and then ask you what you think, if you think it is good, you will receive it.

Dell XPS series go pick one yourself.

I don't know what the difference is between the United States and the domestic one, at present, I've seen the core 2 with a high frequency, and the graphics card should be configured to see how high you need it, relatively speaking, the graphics card is better to choose, such as the N card GTX series.

It's a bit difficult for foreign stuff to do this--

Performance is determined by the clock speed. That's what we call speed ...

Both are very important, and it is better to play the game well (video memory and main frequency are important, video memory determines how much screen content the computer can display, and the main frequency determines the speed...).

It's fast ... But after all, it is a relatively new technology and not very mature. **Expensive... So it is recommended that you buy a 32g or 64g piece and a 240g mechanical one... If you are willing to experience SSD)

4.As for memory,A 4G and 2 2G have a certain difference,It depends on what motherboard you are (some support dual channels,Some don't) If it's dual channels, 2 of the same memory his frequency (speed) is double,One is single speed。。。 Wasted dual channels of the motherboard.

So it is recommended that you use a double 2G...

Absolutely original.

Original Hand hit

1: There are many factors that determine CPU performance, manufacturing process, cache, etc., but it is too complicated to understand it in depth, simply put, quad-core is better than dual-core, in the case of the same core, the main frequency is high, Intel is more stable than AMD, but considering the cost performance, most AMD is better than Intel

2: The video memory of the graphics card is equivalent to a container, the core frequency is equivalent to the things in the container, no matter how big your container is, it is useless to have less things in it, as far as the game you play is concerned, the video memory 1G is enough, GTS450 HD5730 and so on are enough.

3: SSD is not necessary.

4: Almost no difference.

Performance is primarily dependent on the L2 cache size. The second is the external frequency, which is only when the core, architecture, and L2 cache are the same. The higher the main frequency, the better, AMD's CPU and Inter, the settings are different, because Inter has R&D, production, and processor-related chips are all developed, the stability and technical content are higher.

AMD only does CPU, and the process is relatively simple. The strength can only follow in the footsteps of the inter, although on the surface it seems to be comparable. But the intrinsic quality and stability are not as good as inter.

But AMD's CPU has HT technology. A memory controller can be integrated inside the CPU. This is stronger than Inter, and the current i5 and i7 have borrowed from this technology, but it is even more powerful, adding a turbo frequency.

It allows the CPU to turn on different cores and frequencies according to different applications. It's even more out of reach for AMD.

2The graphics card mainly depends on the core frequency, and the memory can be called to replenish the memory if the video memory is insufficient, although it is slightly delayed compared to its own video memory. But core frequency is more critical. Similar to the in-ear caching role of the CPU.

Although it is advanced, the current capacity is on the small side. It's too expensive, and the peripherals can't keep up. Nor can it be fully functional. At present, it is still more affordable for general hard drives.

4.For AMD. Due to the integrated memory controller, the role of one and two memories is not very obvious, but inter or dual channel is better. In this way, there is double the bandwidth, and a memory bar is 128M.

1.The architecture is the most important, followed by the core. Cache, the main frequency can be overclocked, in terms of computing, Intel performance is at least 50% higher than AMD, and the game is about the same.

2.Or architecture,Products of different eras can't be compared,Then there's video memory,1920x1080 resolution to 1G video memory,Otherwise, it's a waste of video memory,It's also a waste at high frequencies。

3.Yes, there will be a noticeable improvement in the speed of daily application.

4.**, timing, voltage.
