Graphics card and memory, upgrade that one is more cost effective, please help a professional!! 50

Look at your graphics card is G8400, it is estimated that your other accessories such as CPU are estimated to be around the E3 series or AMD X2 4 series, the hard disk should be 160G to 250G, such a configuration graphics card can be upgraded to 9600GT 512M (9600GT with AMD X2 5400 is just right), no matter how high the waste is, it is not recommended, the memory is already 2G, which is very enough for your overall performance needs, it is recommended to upgrade the graphics card only.

PS: The 8500GT is called the 9400GT by the NV with a vest, and the performance is less than half that of the 8600GT.

The 9600GT is the native core of the G94, and it can be seen from the numbers that it is the mid-range workhorse positioning of the 9 Series.

The 9600GSO is an "impostor", and its core is actually exactly the same as the 8800GS of the 8 series.

2G memory is basically no problem, you can use win7. Increasing memory doesn't help much for game performance, you can consider changing the graphics card, but the choice of the knife version of the graphics card is not large, depending on the specifications of your original graphics card, it is estimated that you will now change the CPU to a 9600GT or HD4650 knife version of the graphics card, there are many specific brands, refer to your case size and your power supply power selection.

1. The CPU is much worse, replace it with AMD 5200+ 290 yuan, 2. Buy an ADATA DDR800 1G memory module 150 yuan and plug it directly to form 2G memory, ADATA's memory module compatibility is better than any other, Kingston is not good for parallel goods, 3. Replace a sapphire HDG4670 512M DDR2 overseas version of the 3rd generation graphics card 350 yuan or Jieji 9600GT 512M DDR2 graphics card 350 yuan. A total of 790 yuan.

Upgrade your graphics card! No doubt! Enough memory! HD5550 for knife card power saving. If the power supply is good, use the knife version of the GT240

The knife card does not have a high-performance ha, hehe, it's a pity. Only the chassis can be replaced.

The graphics card gives you these:

HD5750 DDR5 1G(HD-575X-ZNF) 830Ԫ.

Memory plus is it.

Your 2 hand cards and chassis can still sell a little, hehe, enough to change to a new chassis Harbin Hangjia Flame 170

What system do you use? XP supports up to 2G memory, it's useless if you expand to 4G, if you change the graphics card, you have to know the motherboard model, otherwise it will be incompatible.

Adding memory is relatively cheap, within 200 pieces, and the graphics card is 400-700 more expensive

What kind of CPU is a CPU?,What do you say about the computer?,If you're an old machine.,Just buy a new one.、It's not much money.The old ones are for your parents.,Because looking at your video memory.,I think your machine can be old.。 A good graphics card in this way may not be of much use. 2G should be enough for memory.

You think about it.

What kind of games to play, if you want some larger 3D games, change the graphics card is the most suitable. If it's ordinary, add memory. Such an economic point.

The performance of G8400 is super bad, so don't give him so much memory, no matter how much performance you share, it won't improve much. It's better to save more memory.

Hello, it's good to provide other configurations, as well as how you want to improve the performance after the upgrade, and what are the main operations in normal times.

Tell lz a good way, HP desktop problems can be directly logged in to the HP official ** select the desktop option for consultation, the engineers here are so professional.

Memory, of course, Kingston.

However, there are more fakes now, so it is recommended to buy ADATA, Jinbang, or Blue Devil.

ps: I have never only bought Kingston, and I have helped my friends buy other brands, such as ADATA, but I don't feel anything when I use it, it depends on personal preference.

CPU needless to say.

Just Intel and AMD.

Other CPUs are not worth mentioning, and it is impossible to say who is good and who is bad, each has its own merits.

PS: Since the CPU entered the dual-core era, I have been using AMD dual-core CPUs

Whether it's your own or for a friend, it's AMD.

In general, I feel that it is a flower intel

2 of 3 for the money to get and intel

90% performance, specifically intelCPU, his logical operation structure is very good and perfect, so his computing power, that is, the speed is faster than AMD's, but its rendering ability is not as good as AMD's, that is, the game performance is not as good as AMD's.

Of course, I'm talking about the low-end grade.

What 4-digit CPU is not in the scope of consideration, not something I can accept**, and there is no need to make it that good.

The sapphire in the graphics card A card is a top brand, and if it is converted to a card, it will be xfx in the N card

It is better to specialize in n card, and in addition.

ASUS's graphics card is also very good, but it's expensive, it's better to buy ASUS quality performance for more than a thousand cards, if you don't buy ASUS for hundreds of graphics cards, it's cost-effective, it's not cost-effective, and it's not cost-effective, add it, Yingchi, Weconex's graphics card is also good, and Gigabyte, Gigabyte didn't make a graphics card after the 6 series, the reason is not very clear, there are too many fakes, and now Gigabyte is back to make 9 series graphics cards, I don't know exactly how, but from the perspective of the workmanship and strength of the Gigabyte motherboard and the previous graphics card, It should still be good, anyway, when buying a graphics card, consider these brands.

Depending on your needs. CPU to Intel

Core i3530, graphics card.

GT240 or GTS250 will do. These games don't burn the graphics card. It's best to have a 2G memory, adding up to about 1500. For others, you can tweak them a little bit to suit your needs.

Just throw away the things from the DDR2 era,

It is recommended to add another 4G to the memory, which can form a 6G asymmetric dual channel, it seems that you want to play games, the larger the memory, the higher the game performance.

Regarding the processor, there are three scenarios:

One is not to change, try to overclock the original processor, the external frequency will be overclocked to 266MHz, and the main frequency will jump to 4GHz! In the case of good heat dissipation, it is not a big problem for the 45nm Pentium, at least it can be overclocked to no less.

The second is to change to a Core dual-core E8400 or Core quad-core Q9300. The former is less than 100 yuan, or about 200 yuan.

Third, this is the most cost-effective solution at present, change to a 45nm 771-pin Xeon quad-core such as L5420 or E5450, they are all core quad-core server versions, 1333MHz high-speed front-side bus, 12M large L2 cache! The former has a low power consumption of 50W, which is equivalent to Q9300, and the latter has a higher power consumption, but has greater overclocking potential, which is equivalent to Q9650. In the past, the Xeon of the 771 interface was transformed into a 775 interface to adapt to the 775 motherboard through the adapter sticker.

Now there is a hard change and no conversion sticker scheme on the Internet, and there is no need to cut the motherboard, just buy it and replace it directly, so that it is foolish and risk-free! 5420 is about 150 yuan, and 5450 is about 200 yuan. Considering that you have a P43 motherboard, you should be able to jump to 400MHz external clock, at which point the 5420 can be overclocked to, and the 5450 can be overclocked!

In terms of quad-core Xeon performance, it is absolutely instantaneous to kill the dual-core and four-threaded i3, which is close to the four-core and four-threaded i5!!

It is not recommended to buy Q9550, close to 400 yuan** is not cost-effective.

One of my own home and one for office use, both L5420 overclocked, chess test about 8000 points. It's all about converting the sticker's scheme, and it's been working very stably for more than a year, and there have never been any problems!

Now is an era of hardware overperformance, new products will be more expensive than the old ones that have been eliminated, but it is normal for the high-end models of four or five years ago to surpass the current low-mid-range performance. Therefore, although it is said that IT products are not old to buy new, if you don't mind, it is of course very cost-effective to let the old products that are old and strong give full play to their residual heat.

Agree with the quad-core Q9550 processor, but the power supply is recommended to be replaced with a new big brand power supply, otherwise I'm a little worried.

The performance is slightly better than the first-generation i3, because it is quad-core, and the i3 is dual-core.

If you don't change the CPU and motherboard, it's a bit difficult to bring the 750. It is recommended to have an extra budget of 300, i3+h61 or h81 is still a good match. If it's cheap, change it to AMD. Direct A10, the graphics card is saved, and online games can be played.

The pins are 775, Q9550 quad-core, and remember to see if your power supply is sufficient.

You can change the CPU of the Q series, and it costs about 200 yuan.

It depends on the purpose of your upgrade.

If you simply want the computer to be faster, a single liter of memory will do.

If you want to play general online games, this graphics card has to be upgraded.

1. It's no problem that the processor can be used for a few years.

2. If the memory is used daily, it is barely enough, if you want to upgrade, it is estimated that you have to find a second-hand one, because this is the memory of DDR2 that has been discontinued. And you have to be mentally prepared on **, it is more expensive than the new memory, because the new memory is DDR3.

3. The graphics card is really going to be replaced, and this graphics card is not as good as most of the current built-in graphics cards.

4. The display does not need to be changed, the inch is good for protecting the eyes, more than 22 inches, it hurts.

Thirteen years of experience in computer maintenance, pure hand-to-hand, hope, thank you!

How much can I afford to invest in an upgrade?

Scores are small things, the key is to help you.

1. After reading your question, first analyze the following configurations:

CPU: Although the Celeron D has a high frequency, but the performance is low, you can consider upgrading to E5700 E5800 E6700Even the Q6600It's best to find a second-hand Core 2 quad-core U.

Memory: DDR2 677 1G Consider replacing and upgrading to DDR2 800 2G 1G for a single strip and get two of them.

DDR2 677 There is not much stock on the market, DDR2 800 1G is still in stock, and the brand new is estimated to kill you for about 100 yuan. This one needs to be haggled.

Graphics: Scaled-down version of the 7300. You can consider upgrading to the 8800 series, 9800 series. These two series of graphics cards are now hard to buy on the market anymore and can only be found on the second-hand market. If you're lucky, some merchants should have stock.

If you feel that this is troublesome, you can directly buy the GT240 GT250 GT430 GT440 on the market. These graphics cards are still available on the market. **About 400, the highest is not more than 500.

2. If you upgrade like this, you need to consider your power rating. Determine whether you want to reach or exceed 300W.

3. If there is anything unclear, continue to ask.

You may not be able to upgrade the memory, graphics card, CPU, power supply or anything else. Especially the graphics card.
