Computer DIY, please point with high fingers, I m stupid, thank you. 20

Thank you for the trust of the landlord and netizens for sending me a question for help.

The ultra-affordability and strong performance of the assembly machine are increasingly popular among the people and are widely welcomed by consumers. However, how to choose hardware and how to achieve the best cost performance is a matter of very advanced hardware knowledge and experience.

The configuration in the above pictures is generally very affordable, and the performance is also very good. However, due to the relationship between dealers in pursuit of profits, it is always the same and inevitable, and they all use smaller memory capacity, two cattle and even miscellaneous hardware. Because if you don't, it will be difficult to make a big profit.

Among these configurations, the CPU is very good, the king of the latest i5, low power consumption, low heat, powerful performance, four cores and four threads, and the integrated HD4600 core graphics card can easily deal with most medium-sized and below games without a discrete graphics card. Therefore, for ordinary users who do not play large games, i5 4590 is the best choice, and its loose piece price is less than 1100 yuan free shipping.

With CPU discreteness, it is necessary to have a heat sink. Although the boxed CPU comes with the original radiator, the heat dissipation performance is not ideal, the noise is also high, and it is expensive, so it is not as affordable as buying loose pieces and buying high-quality radiators.

But in the selection of radiators, these configurations are relatively poor.

For example, low-cost radiators such as Seven Star Ladybug V2 have inherent problems such as loud noise and ordinary heat dissipation performance.

Overclocking III Red Sea Extreme Edition.

Vertical radiators).

You just have to remember that all the heatsinks that lie down on the motherboard have poor performance, and no matter how affordable they are, don't buy them. Only a stand-up radiator can have good performance, which can make your CPU cool and low-temperature, and then reduce power consumption, which is also energy-saving and silent.

But even if it's a vertical radiator, the more expensive the better. Usually 55 119 yuan is fine.

4GB of RAM is simply too small for a mainstream system like 64-bit Windows 7 Ultimate to run smoothly, let alone play games. When the memory capacity of the system is too small, it will have to be forced to open up virtual memory in the hard disk frequently, resulting in a large impact on performance and becoming slower and slower.

The SSDs, discrete graphics cards, and power supplies in these configurations are all unsatisfactory. The game Titan: Red Alert RPO300D, this passive PFC-type power supply, is neither power-saving nor silent. Although the price of about 159 yuan seems to be very affordable, it is not cost-effective at all.

In the picture above, only one of Yingzhong's discrete graphics cards is better, and the others are purely miscellaneous products. The ideal configuration (without a discrete graphics card) should look at least the following:

The best ones are as follows:

If you want to add a discrete graphics card, I recommend that you choose from the GTX750 and above products of Inzon according to your financial ability and the difficulty of the game you want to deal with.

b85+gtx960

More stable, if you want the effect, change the motherboard and CPU, with.

But if you just want to improve the effect, such as smooth gaming, it is recommended to upgrade the graphics card first:

GraphicsMSI GeForce GTX 1050 Ti Gaming X 4G 1290-1493MHz 128bit GDDR5 PCI-E Flagship Red Dragon Chicken Graphics Card.

Graphics card or Gigabyte GeForce GTX 1650 Gaming OC 4G 128bit GDDR5 new gaming graphics card.

The motherboard can be changed for the time being,B85Although the motherboard was four or five years ago,It can't be compared with the mainstream eighth generation、Nine generations U,But it's not too bad,Upgrade the CPU to play the current mainstream large-scale games is still OK,The upgrade plan is as follows:

CPU: Replace it with a second-hand i7-4770 or i7-4790, four cores and eight threads, the performance on the CPU ladder diagram is roughly between i5-7 generation U and i5-8 generation U (as shown below), ** The price of the fragment is about 100 yuan, if you want to save more money, you can also replace it with a server CPU: E3-1230 V3, more than 500 yuan for second-hand fragments, the main frequency is a little lower than 4770, but the performance is almost the same, but 1230v3 does not have a core display, but there is a separate display, It doesn't matter if you don't want to do it.

The graphics card does not pursue the ultimate special effects,As long as you can play, it's enough 960 at present,You can not change it for the time being,If you want to open high special effects on the mainstream large single machine,You can consider changing it to GTX1060 6G。

If you have enough memory, add 8G DDR3 1600 to make 16G

The original 4590 Xianyu is sold second-hand or sold to **CPU second-hand** dealer, and some costs can be recovered.

It's a bit difficult to play a large game with this configuration of yours If you upgrade, the game is mainly to eat the graphics card, and it is more appropriate to replace the graphics card with 1660ti Add a strip of memory 8g so that you can toss the rest, 4th generation i5, and it's no problem to fight for a few more years.

The key is to see what you want to do, the CPU is older, but the motherboard also limits the CPU, the latest CPU cannot be installed on the motherboard, and the memory is also limited by the motherboard, so the key depends on what you want to do, how you plan to upgrade, how much it costs, if in order to play games, once the motherboard is changed, then the CPU, memory, etc. have to be changed, and in order to play games, the graphics card must be changed, so it is better to change the machine directly.

There are no upgrades. Overclocking can still fight for 5 years. The ASUS B85 can be overclocked one notch.

How much are you going to spend? If you want to spend more money, it is better to buy a new one, and if you spend less, it is recommended that you add 8G memory. And then there was no then.

It depends on what you're used for, how to use it, general office, you can barely do it, professional workers have to upgrade some hardware, game professionals, haha, this is going to bleed, the whole set of changes.

The CPU can be upgraded to i7

4790K Xuanbing 400 air cooling can be easily overclocked to 5G, second-hand **1200 or so, others basically do not need to upgrade, such as playing games graphics card is not enough, you can upgrade to 1080 graphics card memory in the last heads-up 8G

The 4590 upgrade to the E31231 makes little sense and the performance is limited. Direct one-step 4790Let's use it until the fourth generation of platform computers retires.

The balance of this configuration is excellent, and it is not recommended to upgrade it, but it is recommended to consider replacing it with a new one.

Due to the limitations of the motherboard, it can only be replaced with i7 or increased memory capacity to make limited upgrades. In addition, your power supply is not good, the output of 12V current is too small, it is difficult to make your graphics card fully functional. (For the power supply of medium and high-end graphics cards, it is recommended that the 12V DC current should be above 40A.)

Choosing a power supply is more than just power! It also depends on the grade of the CPU and graphics card, the higher the grade, the more it needs the support of high-current power supply).

Upgrades are mostly for the game, and if you want to upgrade, you will upgrade three major pieces. Due to the limitations of the motherboard, the CPU has risen to 4790, and it is of little significance to upgrade to 4790K, because the overclocking performance of the B85 motherboard is average. Add another 8G memory, and the graphics card can be upgraded to 1660Ti or 1070Ti.

In this case, it is better to change the power supply.

The CPU is replaced by an i7 4790 or E3 1230 v3, the graphics card is replaced by a GTX1660, and a memory is added to 8G.

This motherboard upgrades the CPU? It doesn't make sense. It's better to let someone else buy a CPU that suits him

First of all, the CPU is the most cost-effective is E3-1230 V2, i5's**, i7 performance, performance really doesn't have to say, it ranks third in the current CPU performance ranking (no overclocking), but i5 3570K, i7 3770K can be overclocked, (E3 can be overclocked).

But your motherboard is B75, this board does not support overclocking, and the memory supports overclocking.

Speaking of hard disks, it is true that the hard disk is large, but you don't consider the seek time, the hard disk speed is recommended Seagate Barracuda 1TB 7200 to 64MB single disc (ST1000DM003).

Number of discs: 1 pc.

Single disc capacity: 1000GB

Number of heads: 2 pcs.

Cache: 64MB

Speed: 7200rpm

Interface type: Interface rate: 6 GB seconds.

Write:< error correction.

I didn't need the optical drive, so I didn't install it.

The top is the graphics card performance ranking, you see, if you don't know it, ask me again.

Motherboards can. Memory suite. It will be 4 g *2. Not bad.

First card recommends an ASUS Matrix HD7970 Platinum Edition case, depending on your particularity. Recommend Enjie Small Phantom or Big Phantom Power Huntkey Multi-Core WD500

Sound card If you're not a sound professional. More than 500 or so will do, and you can also get an SSD for tank rhythm.

Finally, the system needs to be 64-bit.

How good is the graphics card? And what do you do? Depending on the use, the selectivity will also vary.

I just installed a new set of E3V2+B75+HD7870.,Give you some advice:

1. The first set is only suitable for entry-level configurations that are not suitable for discrete graphics cards, and you can ignore them.

2、 The second and third sets are basically the same performance,It's just a difference in configuration,At present,E3V2+B75 motherboard is the most cost-effective configuration,The key lies in the choice of graphics card,At present,HD7850 and HD7870 in the A card are the most cost-effective,I chose MSI HD7870,**1299Yuan to start,The performance is slightly stronger than GTX660,You can basically play all the current mainstream games under high or highest special effects, Island 3 can smoothly maintain more than 30 frames at high efficiency +2AA. If you don't mind getting on a card, you can consider it, of course, if the difference is not big, you can also choose 660. It is recommended to choose Yingzhong or MSI, which is definitely better than Rainbow.

3、Another one is the solid state drive and power supply,The current solid state drive is not too expensive,64G is too small,Install a system and it's over,It is recommended to go to the mainstream 128G,In addition to the 50G installation system,There is also nearly 70G space to copy your favorite and often played games in,A word --- cool! It is recommended to choose from Samsung, OCZ or Puket and other large manufacturers, the quality is more reliable, of course, if you just want to experience it, then whatever, which one is cheaper.

4. The last thing to talk about is the power supply, which must not be saved! The power consumption of the power supply you choose is too small, rated 300W is far from enough, at least it should be rated above 450W, it is recommended that you go to Antec (Antec) VP 450P or BP430, the quality and reputation are very good. Everything else is pretty much the same, no need to change.

1. For the motherboard, the B85 series, ASUS is not recommended, ASUS's high-end motherboard workmanship is better, but the cost performance at the entry level has not been high!! It's better to use MSI or Gigabyte!

2. SSD is recommended to use Pucot, Samsung, and SanDisk Extreme, after all, Kingston is not a professional SSD, and it started late!

3、Graphics card GTX760 is really high or low,I use E3 V3 + ASUS GTX760 Paladin,I feel like I can't wait for it! It is recommended to use GTX970 or wait for GTX960!

4. Kingston's memory module workmanship is still remarkable, but the speed is not high enough! Apacer, Gitch, and Pirate Ship will be better!!

5. 500W is enough for power supply!! Antik's brand is still good!!

6. Personally, I think: you have such a little thing, you don't have to build such a chassis, the small chassis is completely competent. Small footprint and beautiful! Small Chassis Recommendation: Foresight N6, Frost IV, Xianma Charcoal Cube, Firebird Arena!!
