Internet CPU with graphics card N card or A card is better ?

It depends on what you're using it for.

The difference between NVIDIA and ATI refers to the fact that this graphics card uses ATI and NVIDIA chips, and in the past, ATI and NVIDIA were known for their excellent picture quality and fast game speed, respectively. However, with the upgrading of products, the advantages and disadvantages of the two can no longer be simply described in one sentence. First of all, in terms of image quality, since the launch of the GeforceFX series, NVIDIA has achieved a major breakthrough in image quality, although the picture is not perfect, but the difference with a card can only be identified with a professional eye.

After ATI opened the chip, due to the uneven workmanship of various manufacturers, the overall image quality of the product also decreased compared with the original product. With the launch of the GeForce 6800 series graphics cards, NVIDIA has now surpassed the same grade of ATI graphics cards in terms of graphics rendering and picture quality. In terms of performance, OpenGL is NVIDIA's traditional advantage project, in other words, N cards have better performance in OpenGL-based games such as CS.

In some classic games, the N-card also has a faster game speed. In contrast, ATI's mainstream products are currently more focused on DirectX 3D, that is, DX8 and DX9 performance. Especially in the low-end market, the ATI Radeon 9550's DX9 performance is almost twice that of N-cards in the same price range.

However, the newly launched GeForce 6800 series is an exception, and it is important to note that the GF6800 series has a definite advantage in future gaming and entertainment applications due to its full support. In addition, if you need to do professional 3D drawing and rendering, none of the entertainment graphics cards we have come into contact with will perform very well. As for the handling, ATI's All in Wonder is clearly the best option.

Ease of use is critical,Let's talk about the default first,If you're a novice,It's slightly better to choose AIT.,There's basically no need to adjust anything with the driver.,And nvidia's is annoying.,After installing the driver, the resolution is kept at 640*480..And it's nothing if the monitor refresh rate stays there. CRT is troublesome,To manually adjust to85Hz, so it's common to see a lot of people who don't know how to tune it in,CRT has been 60Hz with this aspect of ati is much better,After the driver is installed, it will automatically detect your display and automatically help you set the resolution and refresh rate, and then it's the vertical synchronization aspect,NVIDIA's default is that all games are app-controlled,When playing D3D and new games, the game can be set,Generally no problem,But in some games that don't have this setting, such as CS, it's depressed,FPS has been following the monitor 60Hz and ATI's vertical synchronization takes this into account,The default D3D games are all controlled by the program,And Opergl games are kept off,Play CS can maintain the highest 100FPS。

If you play more games, it is recommended to choose a card of NV, and the card of ATI is better and more stable for monitoring.
