What kind of graphics card is good for such a computer configuration, more than 1G, and more games

What games do you want to play?

What price does the graphics card want? 550ti, 660ti, you can take a look at these models, according to different manufacturers**There are also some changes.

You didn't say how much your power is. 550ti home, your configuration is about 360w-380w. You see how much your power supply is, how to pass about 450w, see how much is rated for the maximum power, say less.

If the maximum can reach 300w, the maximum 400w basically does not need to be changed. If the maximum power is not reached, you will need to replace the power supply. Ensure the stable operation of the machine.

The CPU is a bit scummy, what more games to open? How many watts was the original power supply?

There are two possibilities for installing two graphics cards on the same console: two are exactly the same, and two are different.

The two different ones don't have any performance improvement for the computer, and the only role they play is backup and dual screen. Two monitors can be connected to each of these graphics cards for dual screen output, or it can be used as a backup, and one of them can take over if it is damaged.

Two identical graphics cards can be crossfired, which is: making two or more graphics cards work together, which means that the chipset supports multi-graphics card parallelism technology that can improve the graphics processing power of the system or meet some special needs.

Installation Steps:1First of all, make sure that the specifications of the motherboard slot and the graphics card cheat are the same.

2.If it's not a new motherboard or graphics card, clean all the contacts first.

3.Remove the bezel at the appropriate location on the chassis.

4.Carefully and carefully install the graphics card into the slot, and it must be in place accurately.

5.If there is a bayonet, check whether the bayonet is in place.

6.The screws on the baffle are in place.

7.Power on and install the driver.

8.End of installation.

Graphics card, also known as display interface card, also known as display card, is one of the most basic configuration and important accessories of a computer. As an important part of the computer host, the graphics card is a device for the computer to convert digital-to-analog signals, and undertakes the task of outputting and displaying graphics. The graphics card is connected to the motherboard of the computer, which converts the digital signal of the computer into an analog signal for the display of the display, and the graphics card still has image processing capabilities, which can assist the CPU to work and improve the overall running speed.

For people who are engaged in professional graphic design, graphics cards are very important. The leading manufacturers of graphics chips for civil and military graphics cards include AMD (Supermicro Semiconductor) and NVIDIA (Nvidia). Today's TOP500 computers all contain graphics card computing cores.

In scientific computing, graphics cards are referred to as display accelerator cards.

Normally, a computer can fit one graphics card. However, there are some special requirements that will add an additional graphics card depending on the slot of the motherboard and the capacity of the power supply.

How many graphics cards can be installed on a computer mainly depends on two aspects:

1) The motherboard has several PCI-E slots;

2) Whether the wattage of the power supply can meet the demand, taking GTX660 as an example, the wattage of one GTX660 is 140W, and the wattage of two is 280W, then the power supply should be above 500W to drive two GTX660 graphics cards.

The role of 2 or more graphics cards: two graphics cards are put together, the performance is significantly improved, and the two graphics cards work at the same time to process the graphics information of the same program.

How many memory modules can be installed in a computer mainly depends on how many memory slots the motherboard has. More than 2 memory modules can form a dual channel.

What does dual channel: The CPU can address and read data separately through the two memories, doubling the bandwidth of the memory and doubling the speed of data access (theoretically).

Note: XP system can only recognize, if a single memory is 4G, the second one does not matter, the system can no longer recognize.

Extended Information: Conditions for a Dual Graphics Card Firefight:

1) Motherboard support. Generally speaking, if there are two PCI-E slots on the board, and both are 8x or 16x, you can support a dual-card firefight.

2) Graphics card chip support. The main thing is to have bridges as well.

3) The best brand and model are all the same. The main thing is that the model is the same.

Condition for forming a dual channel: 2 memories can be satisfied.

How many can be installed depends on how many graphics card slots the motherboard can provide, the mainstream motherboard is usually 1-2, the high-end one has 3 or more than 3, and the special board for mining can hold more than 20 graphics cards.

You can fit more than one, but only one can be used.

At this price point, the first model of this ultra-high-end graphics card is the i7 high-frequency dual-core.

Shenzhou Jingdun K580-i7 D1 6999 yuan.

i7 dual-core 4G 500G inch ultra-high-end GDDR5 graphics card Smart switching.

There are others.

ASUS N82EI72JQ-SL 7850 yuan.

i7 processor 2G 500G 14-inch high-end graphics card.

Lenovo Y460AT-IFI (white) 7699 yuan.

i5 processor 2G 352G 14-inch high-end graphics card.

CPU usage.

The discrete graphics card has its own GPU, and a large number of image processing does not need to be done by the CPU, saving CPU time; The integrated graphics card uses the CPU to calculate the image data for you, which occupies a part of the CPU resources;

2. Graphics computing capabilities.

The graphics computing power of the discrete graphics card is much stronger than that of the integrated graphics card, because when playing 3D games, a lot of complex calculations are required, and the integrated graphics card is not enough, in order to exchange for smooth game speed, only to sacrifice the picture quality.

3. Memory usage.

If the memory capacity of the machine with integrated graphics card is not large, the running data will be slower than that of the independent graphics card.

Four: Rendering pipelines.

Integrated graphics cards are generally similar to discrete graphics cards of the same level in terms of operating frequency, and good quality can also be overclocked; However, the biggest disadvantage of the integrated graphics card is that its rendering pipeline is much less than that of the independent discrete graphics card, generally only one or two pipelines, which limits the play of the graphics card, so the fundamental performance is not as good as the discrete graphics card.

Five: Dependency with the main board.

As far as the problem itself is concerned, the discrete graphics card is separate from the motherboard, plugged into the AGP

PCIEX16 slot, while the integrated graphics card, as the name suggests, is attached to the motherboard. Integrated graphics is the integration of the graphics chip into the motherboard, and the video memory is shared in the physical memory. The independent graphics card is inserted in the PCI, AGP, and PCIEX16 slots, with independent graphics chips and video memory.

Six:**. The motherboard with integrated graphics is cheaper than the discrete graphics card + motherboard.

The performance of the graphics card does not depend on the size of the video memory, but on whether the core is efficient. In the same way, CPU performance does not depend on the number of cores, but on the excellence of the architecture, many projects of the original quad-core may not be today's dual-core opponents, especially in games, the current mainstream games have been optimized for dual-core at most, and there are very few games optimized for quad-core, and the effect is not obvious.

Recommendations:1Your motherboard, the graphics card interface is not necessarily easy to use, even if it is easy to use, limited by CPU performance, the best thing is to choose an AMD4830, or NVDIA GT240 level graphics card, no matter how high it is, it will be wasted.

If you want to replace it, only the old products of the first two generations are available, and the Q6600 is the first choice for quad cores. But to tell you the truth, such an old product has been out of production for two years, and the goods are basically repaired, not to mention the quality, and the performance cannot be compared with the new CPU at all, and it is not cheap.

3.If you just want to upgrade a little to play a new game, it is enough to upgrade a graphics card and overclock the CPU, if you want to change the CPU together, this cost is not as good as considering the upgrade of the whole machine.

To be honest, it's almost enough to get an HD4850 1G, or HD5670 (640SP) 1G, and no matter how high your CPU is, it's the bottleneck. To change to 4 cores, Intel Q8300 or Intel Q8400 is recommended for your motherboard. In fact, under the E5300 small super, the memory has risen to 4G, and it is enough to change the graphics card to a mid-range.

It's enough to deal with the mainstream online games now.

Swap 4-core U? 775 has Q6000 series, Q8000 series, Q9000 series, ** more expensive, second-hand are more than 600, but the performance has not been greatly improved, no upgrade value, the current platform graphics card upgrade can consider GT440

Look at the motherboard, and the support, as well as the interface!

Of course, you can add a separate graphics card, you are now using an integrated graphics card, and you can't play large games.

To add a graphics card, it depends on what game you want to play, and how smooth the picture and smoothness are required:

1. High special effects are required, and a high degree of fluency, then at least 1500 yuan or more, GTX760 or above level graphics card.

2. It's just a requirement to be able to play, and the requirements for the picture are not high, but to achieve playable fluency, then you can buy a mid-range graphics card, 1000-1500 yuan level.

3、There are no requirements for the picture at all,Just be able to play,Then the 800-1000 yuan level graphics card can be competent for most games。

Graphics cards below the meta have no playability, they are only suitable for playing online games, and they can't open too many special effects.

Yuan's graphics card can only play 2D, online games, QQ games, and movies smoothly.

The system is changed to win7The graphics card is a set display, you have to change to a separate display, and if you want to play large games, you must at least have a graphics card with a market price of more than 700.

Add a GTX660 and you'll be fine. If you don't have the budget, buy something else.

I don't know what your budget or psychological price point is to buy a graphics card, I will give you the most suitable card at the 3 price points, you can consider it yourself.

400 500 yuan: sapphire hd6670 1GB platinum version (like HD6570 is the same Turks core, with 480 SPUs and 128bit width, its core frequency is higher than HD6570150MHz, performance and HD4830 9800GT and other mid-range cards in the past)

500 600 yuan: ASUS EAH6770 DI-512MD5 (ASUS is the only mainstream performance-level graphics card within 600 yuan, although 512MB is a little smaller, but it is barely enough, at least 800SPU and 850MHz frequency core performance is not HD6670 can be compared).

600 700 yuan: Weconex R6770 Game Master Edition (the only one that uses 6 layers of PCBH6770, with daily chemical capacitors and SO-8 SMD effect tubes, it can be said that the most luxurious HD6770 is it, the default frequency is 900MHz 5000MHz, and MSI's HD5770hawk is the same positioning).

Among these 3 grades of graphics cards, I highly recommend that you choose the best one, and if you go up, you will lose the cost performance (R6850hawk is better to leave it to the X4 9xx series).
