Can anyone tell me that I want to change to a 1G existing graphics card with this configuration, whi

It is recommended that the landlord get the GTS450 of the N card and the HD6750 of the A card. In the larger GTX460、HD6770 is not recommended for the landlord,Because I am afraid that the landlord's power supply will not be able to bring up。 Personally, I prefer HD6750, because of your AMDCPU and AMD motherboard, so A's compatibility is a little better.

Among them, there are many 450 better brands, such as Yingchi, Rainbow, Yingzhong, Weconex, and there is almost no big difference, while HD6750's A card is mainly Blue Treasure and Dilan Hengjin.

However, I would like to remind you that if your computer is still under warranty, you will not be able to use the free warranty after you change the graphics card yourself, so you have to think about it yourself.

Large video memory does not necessarily mean that the performance of the graphics card is good,You also need comprehensive parameters,Large video memory is for the stable point of the frame number of the display,On the 6000 series of graphics cards If you play games, I am more in favor of buying n cards,Because most games are designed with n cards。 n card talk play games gt430 440 The games on the market can basically be played, and it depends on the price you want, go to the computer city to have a look, and then take a look from the Internet**, don't be fooled.

The graphics card is replaced with HD6770 DDR5 1G, Dilan Hengjin and Sapphire are OK, relative to your CPU at this level, no matter how high it is, it can't play performance, and the memory is recommended to add 2G DDR2 800, the price of cabbage is up, don't buy it yet, and when?

Right now. The high and low end of the graphics card has nothing to do with the video memory. 2G also has junk low-end graphics cards.

You can't play this configuration with 2G video memory.

Happy New Year,If you want to upgrade,Personally, I think it's better to choose less than 400 yuan or use the original integrated graphics card,Because the performance improvement is not large,Therefore, it is recommended that if you want to upgrade, the following two models are recommended:

igame440 U D5 512M Q40 (Graphics chip:GeForce GT440 Video memory capacity:512MB GDDR5 video memory bit width:

128bit Core Frequency: 850MHz Video Memory Frequency: 3400MHz )499

Blaupunkt HD6570 1GB DDR3 Platinum Edition (Graphics chip: Radeon HD 6570 Video memory capacity: 1024MB GDDR3 video memory bit width:

128bit Core Frequency: 650MHz Video Memory Frequency: 1800MHz ) 499

If the budget is sufficient, it is recommended to choose a one of about 600 yuan, so that the performance improvement is more obvious, as follows:

Mingxuan HD6770 Transformers (Card chip: Radeon HD 6770 Video memory capacity: 512MB GDDR5 video memory bit width:

128bit Core Frequency: 775MHz Video Memory Frequency: 4000MHz )599

RAUMFENG HD6770 Speed Armor Lizard 1024M D5 (Graphics card chip: Radeon HD 6770 Video memory capacity: 1024MB GDDR5 Video memory bit width:

128bit Core Frequency: 850MHz Video Memory Frequency: 4800MHz )599

Jingying HD4870 1024GD5 Player Edition Parameter Chip Manufacturer: ATI

Graphics chip: Radeon HD 4870

Video memory capacity: 1024MB GDDR5

Memory bit width: 256 bits

zol**499

A 4 500 graphics card is not as good as the previous 1 200 1 200gt second-hand 9600gt or 9800gt despise the upstairs! People say it's cheaper!

I'm more in favor of using the GTS450, and the price is not too high to apply to your configuration. In addition, in the case of the same bit width, you should choose the larger the memory capacity, the better. I recommend one, I hope you like it.

Jingyu GTS450 graphics card 499 yuan graphics card default factory frequency 700 1400MHz

Video memory capacity: 2g

Memory bit width: 128bit

Memory type: GDDR3

Output: HDMI+D-Sub+DVI

Power supply design: 2+1 phase, no need for external 6pin power supply.

Power consumption: 95W

The downside is that it only uses GDDR3. If you want to use GDDR5, the price is nearly 800 yuan.

The last 440 is about the same, but it is not recommended to use the colorful one. Recommended: Weconex, Xunjing, Yingla, etc., are better than Rainbow.

Or on the A card, it will achieve a good effect.

HD7770 Yes, see if the power supply is enough, and you can also add a 2G memory.

To be honest, it's time to change the graphics card, I recommend you buy the HD6770 series as a whole a grade higher than HD6750, ** not much worse.

Your configuration is something from 3 years ago, and the performance is coming first, and it can still be used, and there is also a need to upgrade. Directly add the graphics card HD7750 level of the mid-range entry card is OK, don't look at the video memory to buy a card It's easy to be deceived! Then add a 2G RAM and you can play all the games.

Upgrade: Pay attention to whether the current power supply can withstand it

Embarrassment: Popularize the knowledge of graphics cards to the landlord:

When most people buy a graphics card, they ask how much video memory they have, and sellers also follow the trend. As soon as a recommended graphics card is recommended, the first thing to say is how much video memory is, and the two graphics card parameters of bit width and frequency are rarely introduced. As far as the first parameter of the graphics card is concerned,It's definitely bit width,Not video memory and main frequency,I'll give the landlord an analogy:

Compare the graphics card to a warehouse, the width is equivalent to the warehouse door, the video memory is the size of the entire warehouse, and the frequency is the speed in and out of the warehouse. Once again, the frequency determines how fast you move. Parameter ranking of the final graphics card:

1-bit width, 2-frequency, 3-video memory!

Based on the above introduction, let's talk about what kind of graphics card is suitable for the landlord's machine! Most people change their graphics cards because they are unhappy playing games, and it is estimated that the landlord is also a problem in this regard, so the first choice is to change the N card [NVIDIA, GT series], looking at the landlord's CPU, AMD Athlon240, this CPU with 600 yuan below the price of 128-bit wide video memory 1G graphics card has no problem! It's a bit tiring to think about it!

Between the CPU and the graphics card, there can be no relationship between a small horse and a big cart! That would be a huge waste of resources! The landlord can consider zotac, Yingla, Xiangsheng and other brands, do not recommend Rainbow, Colorful graphics card at this price, it is OK when it is new, and I love the screen when I am a little older!

Hope it helps the landlord!

I --- the company's network management!

The most affordable is still the last 5770 The performance is the same as the 6770 **Also cheap 6770 is a 5770 vest card.

The platform is too low, and it's useless to fix it.,Oh, if you don't like it, spray it!

gt630。。No matter how high you are, you can't use this configuration. Add 2G RAM.

Let's change to an N card, 5 or more is OK.

Only changing the graphics card really doesn't help, it doesn't improve the performance of the computer, it is recommended to change the graphics card, motherboard, and CPU together!

Your 641 quad-core, suitable for 7750 499 yuan -GTX750Ti 999 yuan graphics card, of course, the memory must first add a 4G 1600 230 yuan memory to talk about the graphics card problem.

Just run a game like lol, choose a second-hand 5750 DDR5 512M 150 yuan, this is the most money-saving, Master Lu runs points, you can fully open lol, power consumption 86W, the power supply needs to meet the rated 270W or more. A card is not fake, if you plan to buy an Nvidia graphics card (n card), there are too many fakes, there is no ability to distinguish, or don't look at it.

** Buy a second-hand Sapphire 7850 graphics card, 499 yuan, Master Lu runs the score, it is a blind Li Yu advanced graphics card, you can run all games, but your CPU performance can only run medium-sized games, 640 quad-core running large games are general, and the special effects are not high.

7850 power consumption 130w, your configuration power supply needs to meet the amount of more than 330w, new graphics card, look at the sapphire 7770 599 yuan, Master Lu running score, power consumption 80W, this is the most similar graphics card with 640 quad-core, running medium-sized games is good.

R7 260X 699 yuan, Master Lu runs the score, the power consumption grinds Li Chi 115W, the sex can be strong, but the CPU performance is not powerful.

3.Second-hand power supply Great Wall Quad Core King BTX500S rated 400W 80 yuan.

If the power rating of the power supply is insufficient, the graphics card shall not be forced, and it will burn up.

1.Weconex R6750 512MB Extreme Edition.

Recommended reason:500The strongest performance graphics card within the yuan,It maintains the frequency of the public version6750,GPUbuilt-in720 stream processor,The core video memory working frequency is700 4600,The performance is much stronger than the sapphire HD6670 512MB extreme version at the same price,The gap between the two is about 50%,It's not a level at all., The 16 ROP units make the 6750 easily capable of most 3D games at 1680x1050 (of course, there are trade-offs to the effects, but Call of Duty: Modern Warfare 3 is a game that can turn off anti-aliasing and then turn it all on, which is very smooth).

2.Sapphire HD6670 512MB Extreme Edition.

Recommended reason:There should be a lot of brand control who will buy this,Although the performance is not very reasonable,But it's good to rely on480SP+800MHzThe core frequency supports the scene,Much stronger than the previous generation HD5670 480SP version,It won't lose to HD4830,The only pity is that there are too few ROP units,And the memory frequency is low,Many games run uncomfortable in a high-resolution environment。

Zhengzhou Kunteng Software and Hardware Technical Service Department provides:

Friends, in terms of the configuration of your computer, you can add a GT630 1G graphics card, ** is about 400 yuan, and the performance of the high-end graphics card cannot be played better!

6770 599 yuan or so Spike all kinds of large-scale 3D, or GT550 can also be cost-effective not as good as the above one But it's not difficult to use

A graphics card under 300 that feels about the same as you feel is not worth buying.
