I want to change the graphics card in the past two days, 600 700 or so, N card or A card, I don t kn

The 8600GT card is all around. If you want to be the most important, just look at the parameters of each aspect.

Game n card Movie A card !!Each has its own spring and autumn!!

Hello landlord!

Whether the N card is better or the A card is better, let's not evaluate it first. As far as the two graphics cards you gave are, of course, 7770 good. Strictly speaking, the 650 is an entry-level graphics card, and the 7770 is a mid-range graphics card. To be precise, they are not at the same level.

Let's take MSI as an example (same brand):

MSI N650 Power Edition Specifications:

Video memory capacity: 1024MB

Memory bit width: 128 bits

Core frequency: 1124MHz

Video memory frequency: 5000MHz

Stream processing units: 384.

MSI R7770 Power Edition Specifications:

Video memory capacity: 1024MB

Memory bit width: 128 bits

Core frequency: 1100MHz

Video memory frequency: 4500MHz

Stream processing units: 640.

All else being equal, the 7770 has a lot more stream processing units than the 650!!

What does the stream processor do (does it matter): For example, the stream processor is equivalent to the worker mixing concrete, the video memory capacity is equivalent to the mixing plant, and the bandwidth obtained by bit width and video memory frequency is equivalent to the vehicle transporting concrete. This shows the role of stream processors and bit width.

Sincerely, I hope you will adopt!

The HD7770 is noticeably more powerful. GTX650 is equivalent to HD7750 at most, and HD7770 is better than HD7750! Choose the one you want.

The N-card is better than the A-card for most games.

Intel's U selects N card, AMD's U selects A card, the performance is not too bad, and the main stability is the main one.

Now the low-end entry-level graphics cards also have relatively good game performance, in the face of a variety of 3D online games and stand-alone games can be handled, typical representatives are GTX650, HD7750, not only play games are basically qualified, but also the power consumption is lower than the previous low-end card, you don't have to worry about your power supply at all.

The main ones I recommend are 3: Sapphire HD7750 1GB Platinum Edition, Yingzhong GTX650 Ice Dragon Edition, MSI N650Ti Hawk, the performance of these 3 cards is improved from front to back, and the performance of N650Ti Hawk is even the same as HD6870.

If you often run3D stand-alone games,The pursuit of high image quality and smoothness,Then Yingzhong GTX650Ice Dragon Edition is a compromise choice,**About 700 yuan,Because the frequency is higher than the level of the public version,Performance is basically equal to HD6850(But the power consumption is lower),I think you are very suitable with this card,Taking into account all aspects of the situation。 If you plan to ask for the N650Ti Hawk, then this card** is almost 1000 yuan, which may seem a bit expensive, but the performance is indeed quite ideal.

As for sapphire's HD7750,It's completely the public frequency,No highlights,It's better as an alternative,This card is a huge shipment,Its status is the same as the previous generation HD6770,Specifically for those who don't want to spend more money、But can't accept players with low performance,This card** is also 700 yuan,Physical stores may sell 800 yuan,Cost performance can only be said to be average。

This one I've been paying attention to, there are two AMD 6850, NVIDIA's GTX560SE. 6850 is more recommended, and it is recommended that the landlord choose a card of first-line brands such as Sapphire, Dilan Hengjin, and Xunjing. **Almost, the specific model is not given.

What do you want a graphics card for this price range?

Litai GT430 2048M DDR3---599 yuan.

Gengsheng GT430 Red Tassel Edition 1G D3---549 yuan.

Blaupunkt HD6750 1GB GDDR5 Platinum Edition 699Ԫ.

Weconex R6750-HM1024GD5 speed version 599 yuan.

Dilan Hengjin HD6750 Hengjin 1G 699 yuan.

The above three are enough for playing games, but they are still slightly insufficient for large networks and stand-alone games, because the video memory width of these graphics cards is 128bit, which is a grade worse than the HD6790 graphics card above 700 yuan.

This graphics card is excellent! The only flaw is that it doesn't support DX11 games, but because DX11 games are not very few now, this graphics card can kill all the games currently on the market, and it can also turn on the special effects. Now the price is 650 yuan.
