Do you need to buy a sound card and graphics card when you buy a computer?

The sound card motherboard comes with it, and the graphics card is generally bought, and a few are integrated with the motherboard. If you have high requirements for sound effects, you should buy a good sound card. If you're just surfing the Internet or playing mini-games, then use a motherboard with integrated graphics, it's cheap.

Sound cardAll motherboards come with their own (that is, integrated, called integrated sound card).

Some graphics cards have motherboards, some don't, it is recommended that you must buy, it is too important for games, if you don't like to play computer games, you can choose a motherboard with integrated graphics, but you must have, because the graphics card is a device that transmits signals to the display, if even the motherboard does not have an integrated graphics card.

Then you don't have a place to plug in your monitor, hehe.

Today's motherboards generally have an integrated sound card, not necessarily an integrated graphics card!

It depends on the needs of the individual, for example, if you mainly play online games, you need a discrete graphics card, just an integrated graphics card for office study and watching movies can be satisfied!

Depending on your needs, there is no need for a sound card, if you want to play games, buy a graphics card.

Play games and play graphics cards, and the loser buys a sound card There are graphics cards and sound cards in the motherboard!!All motherboards have sound cards, but not necessarily graphics cards!

The motherboard will have an integrated sound card, but not a graphics card, and you need to use a discrete graphics card or an integrated graphics card in the CPU.

Integrated graphics cards generally do not have video memory, but use a part of the main memory of the system as video memory, and the specific amount is generally automatically and dynamically adjusted by the system as needed. Obviously, if you use an integrated graphics card to run a lot of memory-intensive space, the impact on the entire system will be more obvious, and the frequency of system memory is usually much lower than that of a discrete graphics card, so the performance of an integrated graphics card is inferior to that of a discrete graphics card. Motherboards that use chipsets with integrated graphics cards do not have to use integrated graphics cards, and motherboards can completely shield the integrated graphics cards, but for cost reasons, this is rarely done.

Sound card (sound card) is also called audio card (Hong Kong and Taiwan call it sound effect card): sound card is the most basic component of multi-technology and is a kind of hardware that realizes the mutual conversion of sound wave digital signals.

The basic function of the sound card is to convert the original sound signal from the microphone, tape, CD and vertical mold, and output it to earphones, speakers, amplifiers, tape recorders and other acoustic devices, or make the instrument sound beautiful through the ** device digital interface (MIDI).

Graphics card is one of the most basic components of personal computers, which is used to convert the display information required by the computer system to drive the display, and provide progressive or interlaced scanning signals to the display, control the correct display of the display, and is an important component to connect the display and the motherboard of the personal computer, and is one of the important devices of "man-computer dialogue".

Now motherboards have integrated sound cards.

The integrated graphics card is integrated in the northbridge chip of the motherboard, and the video memory is divided from the memory, and there are also motherboards with integrated video memory.

A discrete graphics card is just a card = = the expression is not clear.

Without an integrated graphics card, it is allocated from the memory to make a graphics card, and independent is a separate graphics card, which has nothing to do with the memory, and the motherboard has nothing to do with it.

The motherboard with integrated graphics is integrated with the motherboard, and a discrete graphics card can also be installed, which will generally automatically block the integrated graphics card. Of course, it can be used without installing a discrete graphics card. This is a cheap and affordable product launched by the manufacturer.

Almost all motherboards integrate sound cards, network cards. The installed accessories are generally CPUs, motherboards, hard disks, memory, graphics cards, chassis, power supplies, optical drives, monitors, keyboards and mice.

The integrated graphics card is integrated with the sound card and the motherboard, what does it have to do with the memory?

It's just that this kind of motherboard** is cheaper, suitable for office use, and if you play large games, it is recommended to use a discrete graphics card.

Both the graphics card and the sound card are separate and integrated.

As the name suggests, the integrated one is the one that comes with the motherboard.

Nowadays it is generally used independently.

Installed accessories: motherboard, CPU, fan, graphics card (discrete), memory, hard disk, power supply, monitor.

The motherboard will have a sound card chip integrated.

And there are independent interfaces.

Although the sound effect of today's onboard sound card is already very good, but the original independent sound card has not disappeared because of this, and most of the current launches are tailored for **audiophiles and other special occasions, it has quite strict requirements for some technical indicators in electroacoustics, to achieve the degree of excellence, and with an excellent playback system, it gives people the best audio-visual enjoyment.

Whether or not you want to install a discrete sound card is decided according to your individual needs.

If you don't have any requirements for sound quality, then whether it's the motherboard's own onboard sound card or the graphics card's own HDMI sound card, you don't need to buy a separate sound card, unless you're that **audiophile, then you need to buy a high-end independent sound card. The sound quality of an ordinary sound card is not as good as that of a high-end standalone sound card.

There is no need to buy a separate sound card, if you have high requirements for sound quality, you can add a high-end independent sound card.

If you can ask like that, you just don't.

If there is no special purpose, the integrated one is sufficient.

It depends on your role and budget. And what is the computer. I just knew.
