My configuration E5300 dual 1G total 2G integrated g41 cad is very stuck

First, I don't know if you have an internet speed card or if your computer feels slow! ~

Second, if the network speed is slow, it basically has nothing to do with the configuration of the computer, and now the network card in the general computer is supported, so it will not be caused by the computer configuration to cause the network speed to be slow, the slow network speed is mainly reflected in the 1 **slow speed, under normal circumstances, the network speed of 2m is about 200-240kb.

Third, if you feel that the computer is running slowly, there are many possibilities, the most common is that the system disk space is too small (the system disk is the C disk) you can see how much space is available, under normal circumstances, at least 65% or more, otherwise it will affect the running speed of the computer, but if you are a novice, it is recommended not to delete the things in the system disk, especially the things in the windows folder! There is also a way to play games that feel that the picture is not smooth, and the game is very slow to start, which is generally 3 possible 1 memory is too small 2 graphics card video memory is small 3 CPU is too low.

The landlord should not be too detailed for you, I can only guess and hope to help you, if you still have questions, you can ask me questions!

The network speed is very stuck, and there are generally several situations: First, your machine configuration is low, second, your network speed is slow, and third, your machine makes unreasonable use of space to the machine, and the response is slow.

Due to the performance limitations of the E5400, HD5770 or lower GPS450 graphics cards are suitable for you.

The HD5770 1G version is basically around 800-1100, and MSI's HD5770 Hawk is 999 online shopping**.

If you don't overclock, it is rated at about 250W power consumption, and you need a 300W rated power supply to be more stable.

And the 899's Shadow GTS450 Black Edition is also good.

If the budget is less than 800, then the 1G HD5750, Weconex R5750 1G Gaming Master 699 is very cost-effective. The 699 can only be bought for the GTS450 with 512MB. The power consumption is about 20W lower than that of HD5770.

Dilan Hengjin HD5670 Extreme Edition The second-generation 1G version is also 799, 640SP high frequency and HD5750 performance is also comparable.

599 first file is recommended sapphire hd5670 extreme version 3rd generation or dylan hengjin hd5670 extreme version second generation 512mb version, 640sp high frequency. 1G video memory belongs to games like GTA4 and Crysis, which occupy video memory, and generally 19 LCD 512MB video memory is more than enough. The reason why N card is not recommended at this price is because there is no N card below that can be compared with A card, GT240 performance is not as good as 9600GT, does not support DX11, and the heat is higher than that of a card in the same grade, so it is not recommended.

The lower is the HD5670 400SP version of the 499 512MB DDR5 video memory, the king of performance below 1,000 yuan is the world of 128bit DDR5 video memory, about 60W power consumption, 3600MHz 128bit DDR5 bandwidth is equivalent to 1800MHz 256bit DDR3 video memory bandwidth, so there is no need to worry about whether the bit width of the video memory is 256bit. The GT430 supports DX11, but** has no advantage over the HD5670.

If overclocking recommends a rated power supply of more than 350W, buy an 80PLUS energy-saving Antek BP-430 power supply online 299

You don't need to change the power supply to install the GT240 If you can change the power supply, use the Sapphire 5770 ** version 680 (recently dived).

N card is OK, 512M power supply must be greater than 200W
