If you want to replace the CPU and graphics card on your computer, you can only change the CPU and g

Do you want your motherboard to support PCIe graphics cards? If not, it's harder. AGP is mostly out of production.

It is best to use CPU-Z software or EverestCheck what the motherboard supports, such as single-core or dual-core. Before making a purchase.

In fact, the motherboard is the cheaper of these hardware, and you upgrade your computer to only upgrade the CPU and graphics card.

If you don't upgrade the motherboard, you will lose money on investment.

There is no need to change the CPU, as far as your requirements are concerned, it is completely sufficient;

Graphics cards consider GT440 and above or 6670 and above is sufficient,**Start at 450.

What do you do with the computer,It's OK to change the graphics card to play games,Onda HD6570,**499 yuan。 No problem with large 3D games. You don't have to change the CPU, your graphics card is enough to play.

The CPU can't be boosted very much, it's already okay. Unless you change to four cores. For example, Q6600

The graphics card can consider the GTX550Ti 700 or so.

As for the GT440 and the like, it's not necessary, and the improvement is not obvious.

It depends on what you're using it for, if it's used to play big games, the CPU can be changed to a 4-core 8-series one, and the graphics card is 5750

If you're just watching a movie and playing a mini-game, you don't have to change the formula.

The CPU can be swapped for E5700

As for the graphics card, you can change it to GTX550Ti or above, but pay attention to the power supply voltage.

OK. Because the CPU has the biggest impact on the performance of the computer, changing the graphics card may be due to gaming and image processing problems. Basically, if the CPU and graphics card are better, the overall performance of the computer will go up.

CPU: ** processor (CPU, English: CentralProcessingUnit), is one of the main equipment of electronic computers, the core accessories in computers.

Its function is mainly to interpret computer instructions and process data in computer software. The CPU is responsible for reading the instructions, decoding the instructions, and executing the core components of the instructions.

Graphics card (videocard, graphicscard) is the full name of display interface card, also known as display adapter, is one of the most basic configuration and important accessories of a computer. As an important part of the computer host, the graphics card is a device for the computer to convert digital-to-analog signals, and undertakes the task of outputting and displaying graphics. The graphics card is connected to the motherboard of the computer, which converts the digital signal of the computer into an analog signal for the display of the display, and the graphics card still has image processing capabilities, which can assist the CPU to work and improve the overall running speed.

For people who are engaged in professional graphic design, graphics cards are very important. The leading manufacturers of graphics chips for civil and military graphics cards include AMD (Supermicro Semiconductor) and NVIDIA (Nvidia). Today's TOP500 computers all contain graphics card computing cores.

In scientific computing, graphics cards are referred to as display accelerator cards.

It can be seen that the CPU and graphics card have the greatest impact on the performance of the computer, so it is okay to only change the CPU and graphics card.
