I want to upgrade the graphics card with good mid range left and right performance that suits me

Why change the configuration of a good one, since you want to change it, change it all.

At present, the distribution of "mid-range" graphics cards that are suitable for matching 955 and are more cost-effective is:

HD7770 (more than 700 pieces), GTX650Ti (900 pieces), HD7850 (1000 pieces), HD7870 (1300 pieces).

The above are sorted by increasing performance, and you can choose according to your budget.

Other parts: Currently** is 600 blocks.

2. Don't buy this motherboard, this M4N98TD EVO shipment is very small and has been out of production for a long time, and most of the ones you buy are repaired. You can consider the MSI 970A-G46, ** within 500 pieces.

3. Western Digital 500g blue disk** is 350 pieces.

g 200 pieces of God.

5. Cooler Master 500W power supply with bronze 360, 270 without bronze these things add up to about 2000 yuan, you choose a graphics card to add up to the total price.

955 with 7850 and even 7870 GTX660

The pressure is not very high, and only a very small number of games with particularly late single-core performance will have bottlenecks, but there are almost no games that can eat up the 955 single-core

7750 bar,This kind of ** is more suitable.,And your overall performance is also more matched.,If you just play games, you can open anything else with a better card.。 It is estimated to be 2300, and it is recommended that the power supply be rated at 350W. I really can't do it, I'll help you save a new one.

Play online games on 7770 down, GTS450 6770 5750 are enough.

Play a stand-alone machine on 7870 up,Now 7870 1G video memory**Very good,It's worth starting,You can look at GTX660TI again,But it's estimated that ** is not very strong,I'm afraid that the price will drop after buying。

Sapphire 7770 black diamond, the best choice.

Although the current CPU of the landlord is quad-core, the main frequency is low, only, so in practical applications, it will be weaker than the performance of high-frequency dual-core U, which is especially obvious in single-threaded or dual-threaded tasks.

With the computing power of your current CPU, the graphics card is recommended: the price of about yuan, the performance is very strong, and it is more compatible with your current hardware, there are no shortcomings.

Main parameters: bandwidth, pixel texture fill rate spSupport W7, support the latest DX11 special effects under W7 system.

Full load power consumption 165WThe current configuration requires a power supply rated at around 350W to ensure stable operation.

With such a configuration, the special effects of mainstream online games can be fully ensured. The extent to which the special effects of stand-alone games are turned on requires different analysis and testing of different games.

Hope it helps.

PS: If you want to upgrade the system to W7, then it is recommended to use a 64-bit operating system, and add a 2G DDR2 800MHz memory to the memory module. In this way, the CPU has been upgraded from 32 bits to 64 bits, and the computing power has been doubled.

32 bytes at a time becomes 64 bytes. When the memory is dual-channel, the data transfer speed is also doubled. In this way, the overall performance of the computer will be greatly improved.

And from the current point of view, the 4G memory can still cope with the W7 system.

Your previous memory module was ADATA, and ADATA is a very good memory module with the best compatibility. So you can buy another one of the mighty ones. Second-hand**115 yuan, this ** can be bought in a physical store. If you don't sell one, you will change it.

The GTX460 is an N-card. That is, the graphics card of Intel chips. In this way, your u, board, and graphics are all Intel's, which can also minimize the incompatibility between hardware and improve the performance of hardware.

GTX650 or HD 6770 7750

It's best to buy another DDR2 800MHz 2G memory.

The memory is added to 4G, and the graphics card recommends the 600 series, because it is 28nm, the power consumption is much smaller, just 650 or 650ti.

It turns out that the graphics card is sapphire, and you will add a sapphire hd6850 memory and a 2g group of dual channels.
