How to buy Good quality Graphics Card guide.

Here are some things to look for when selecting a graphics card

Number of transistors: The more transistors there are on the card, the less noise there will be, the better the video will be filtered.

Clock Speed: The better and more it is, the better the performance.  Take a look at it.

Memory: I have discussed this before.  Now 1 GB to 4 GB cards are available.  See what it takes according to your type of work.

Memory type: DDR, DDR2, GDDR3, GDDR4, or see GDDR5.  The better, the better the performance.  However, the price of GDDR5 is a little higher.  Be aware that it has nothing to do with your motherboard's RAM DDR2 or DDR3.

Bus speed: Memory bus is how much data the processor works with at once.  If there are more buses, you will get output very fast.  Again, if the bus is too much, the cost of power will be more, on top of that, if your monitor is small, the bus will be unused.

PCI version: See which slot of your motherboard and buy it.  Suppose your PCIe x8, but you bought PCIe x16 2.0.  Then there is no way but to give it to someone.

DirectX support: DirectX is a unique addition to Microsoft.  It is essential for new hardware, video acceleration.  The new version 11.  So see if the graphics card supports the new version of DirectX.

Pixel Shader: Pixel Shader is needed to highlight the comparative processing and properties of different levels of pixels and light.  See how much your graphics card supports.  There are currently 5 versions.

OpenGL: This is a combination of numerous library functions for video processing, which speeds up the output.  When buying, see if it supports and how many versions.

Anti-aliasing: It can be used to remove blurred or blurred images.  It is used in many games and apps.  So see if you have this feature.

Max Output: If your monitor has a resolution of 1600 by 1200, then you must not buy graphics with 1024 by 6 output.  At present the output of all cards is between 1800 by 1200 to 2560 by 1800.  So it's not a big deal at the moment.

Power Factor: See how many watts the card wants to supply.  If you can't give the required power, you will get stuck going to work.  There may be damage.  Usually 400 to 600 watt supply is required.  Update your PSU if needed.

Multi-output: This is what you need if you want to watch on two or more monitors at once.  Notice that almost all cards have two or more ports.  These are provided so that it can be viewed on all monitors at the same time.

Refresh rate: See what rate you will get the output, i.e. how many Hz video will come on the monitor.  Its default value is 80.  However, spots or flickering below 60 can be seen on the CRT monitor.  Some monitors are not able to show below 75 Hz.  So take a look at what you need for your monitor.

Multi-GPU: This is for die-hard gamers.  If you are not satisfied with a video card, then buy a card that can fit more than one card.  And you also have to buy a motherboard that supports multi-GPU.  Both Nvidia and AMD make multi-GPU system supported chips.

Energy Saving: Keep an eye on whether your chip is working as well as raising your electricity bill by corruption.  For this, buy the card by looking at the rating of Energy Star.

Software Support: Check to see if you can get the card driver on the system you work on.  Now AMD is offering official drivers for Windows, Linux and Mac.  So the choice is yours.
