Desktop Hardware Refresh, Desktop Hardware Refresh Cycle Discussion

There is no need to add 4G of memory DDR2. Memory is also more expensive.

The CPU is really dragging down the whole, and the motherboard can't support the new CPU either.

Change to an HD7750 graphics card with high performance and low power consumption. Improvised to play. More than 600 yuan.

Replace the motherboard memory. A8-5600K + A75 platform + 8G DDR3-1600 dual channel. 1300 yuan. The new APU is a bit stronger than the HD4670. The old platform can probably get a lot of money by selling the CPU motherboard memory.

If the 790 motherboard is not replaced, the big platform is not replaced. CPU for AMD640 (quad-core) is enough, about 550 yuan, too high, unnecessary. Graphics card: AMD platform, choose a card series.

Personally, I think that the requirements for large stand-alone machines are not very strict, and the picture quality is not very strict, and it can be used6670 6770 or the like, about 500-600 ** is not expensive, and the cost performance is okay. If it's a little better, change the 7750 7770 to about 600-800 more, and the performance will be better. There is no need for thousands of graphics cards.

Platform Limitations. MemoryXP and win732 bits are sufficient, and these two systems can only recognize 4G. Your 64-bit system will need at least 8GB of RAM.

The memory is currently very cheap and more than 100 yuan. This will not exceed 1500You don't have a large number of movies, a large number of stand-alone machines are enough, and you can not change them for the time being.

First of all, you have to know that the motherboard determines everything, you take 1500 to replace the outdated Dongdong, do not change the motherboard, it still makes no sense, either the power supply in the chassis is all replaced, or it will be used, you have no substantive meaning to change it like this!

Hard drives, updates are not fast. Now many years ago, hard disks are not still used, and the speed of mechanical hard disks has been bottlenecked, so the update cycle is much longer. The new hard disk is developing in the direction of higher capacity, and the higher the capacity, the higher the magnetic density, and the better the performance.

The power supply is also a slower update accessory, and it can be replaced in 5 years, 8 wrong, except for the broken one. The power supply is developing towards conversion efficiency, and of course, it is quieter, energy-saving and environmentally friendly.

The keyboard and mouse are consumables, and if they are broken, they will be replaced This depends on how you use it, and it will be replaced once a year if you use it fiercely! Mechanical keyboards will get cheaper and cheaper, because more people will use them. Keyboard backlight is also a trend of the future, and wireless technology keyboards and mice are expected to be popular in the future.

The display also takes a long time. It's no problem with a 3 to 5 years! The display is developing in the direction of 3D wide color gamut, and more high-resolution displays will be released in the future! Retina screens will move from flat panels to civilian displays. Of course, this process will be slower

Desktop computers are designed to last for 9 years, so as long as the hardware is not damaged, it can be used forever. However, computers are not eliminated because they are damaged, but mostly because their performance cannot meet their needs. If your desktop PC is configured to meet your needs, you don't need to update or replace a more powerful accessory.

The following is a brief description of the computer configuration and corresponding performance:

1. Dual-core processor + 2G memory + integrated graphics card + mechanical hard disk. The performance meets the requirements of small games such as surfing the Internet, watching movies, chatting, office, and playing chess;

2. Quad-core processor + 4G memory + independent graphics card + mechanical hard disk. In terms of performance, it can meet the requirements of surfing the Internet, watching movies, chatting, working, drawing, playing stand-alone games or online games;

3. Quad-core processor + 4 8G memory + mid-to-high-end independent graphics card + mechanical hard disk or solid state drive. In terms of performance, it can meet the requirements of surfing the Internet, watching movies, chatting, working, making pictures, playing large-scale stand-alone games or large-scale online games;

4. Six-core processor + 8G or more nickname + high-end independent graphics card + mechanical hard disk or solid state drive. In terms of performance, it can meet the requirements of surfing the Internet, watching movies, chatting, working, making pictures, and playing large-scale audiophile-level stand-alone games or large-scale online games.

Hardware manufacturers generally release new products every year, such as Intel will release a new platform, and the corresponding CPU, motherboard, and memory will be upgraded. The same is true for graphics cards, even if the product line is not updated, it will still follow the new corresponding driver.

I do PCB design and program development.

I bought the first computer in 1997 and this year I have upgraded it three times in two years, and my upgrade experience is that I changed a monitor in 2000, and then I upgraded it every time, only the motherboard was replaced, the memory, the CPU, the graphics card, and the power supply were modified by myself, and the hard disk is usually based on high chances, so to answer your question, computer peripherals, and if the economic conditions allow, I will change one, but I still like to spend my money on the cutting edge.

As long as these are not broken, they basically do not need to be updated.
