How important is a graphics card? Very important, of course, for those who play games or design, if you just do office work, then you don’t need a video card, and you don’t need to look down. Most people buy graphics cards based on price, brand, and model. Usually, these three conditions can determine which graphics card they need. However, there are so many options for graphics cards that it's not enough to simply understand. So, today I will teach you how to look at a graphics card from a scientific point of view.

Firstly, this is architecture of video card. Whether you're buying a new graphics card or a non-old graphics card, newer graphics card, better. Of course, if video card is same, you will have to compare other parameters.

For example, if other parameters match:

1. Stream processor, higher value, better.

2. Core frequency, higher better.

3. Video memory, more better.

4. Bit depth: more, better.

If you don't understand these things, then only thing you can look at is price. The higher price of graphics card, stronger performance will be. How much you can pay, then just choose a graphics card according to that amount, because that suits you best.

Despite fact that RTX20 series graphics cards have been released, price is too high, and specific performance does not allow jumping to conclusions, so recently GTX1050Ti, GTX1060 6G/5G/3G, GTX1070 graphics cards have been mainly installed. /1070Ti, GTX1080/1080Ti and AMD only has RX580/590. So choice is very simple. Generally, N cards are main choice. If you are poor, choose GTX1050Ti. It can handle over 90% of major online games and some of latest offline masterpieces. If you have enough budget , GTX1060 6G is best choice. If you have a lot of money, choose GTX1080/1080Ti.

I believe that many people will have four problems when choosing enough graphics cards.

The first question I mentioned above, should I choose card N or card A? The current main graphics card is N card. Of course, it still depends on your own needs. If you need to recommend it, you should choose N card.

Secondly, do you need a video card with a backlit effect? The heat dissipation backplane can improve cooling capacity of graphics card, so backplane is necessary, but lighting effect doesn't matter unless it's color management.

Third, is it worth spending money on brand value? ASUS graphics cards are most expensive among many brands, so why is such an expensive graphics card better? At very least, author believes that this is more of a bonus for faith: for same price, you can only buy GTX1080Ti from ASUS, so you might as well choose Titan X from other brands.

Fourthly, how to coordinate video card with processor? You wrote about this issue, you can read: Generally speaking, low configuration is low, medium configuration is medium, and high configuration is high. If budget is limited, it simply means that there is no money, either price of video card is twice price of processor, or price of processor is twice price of video card.
