5 Reasons why you should buy a dedicated graphics card

Graphics cards5 Reasons why you should buy a dedicated graphics card. Question from Dev Katyal: Hi GadgetBhai! I really love your website, especially the suggestions and tips. Please help me with your suggestions this time.

I’m shopping around for a new desktop computer (assembled) and I’m aware about the advantages of higher RAM and faster Processors, but I have a strong doubt regarding a graphics card.

Is it really helpful to buy a computer with a stand-alone dedicated graphics card rather than using the integrated graphics usually seen in all mother boards?

Thanks in advance for your tips!


Gadgetbhai Kish’s answer: Dev, there is a fairly straight forward answer – it depends.

It depends on what you plan to do with the computer. For most users, systems that have integrated graphics (inbuilt in the motherboard) are more than sufficient, but there are specific scenarios where a discrete dedicated graphics card would be a big plus, if not necessary.

It is a given that almost any graphics intensive application will benefit greatly from a dedicated graphics card.

Even the latest PC motherboards with integrated graphics will not be able to keep up with with modern games, and the problem is compounded when you plan on doing any studio jobs like video editing or photoshop’ing regularly or if you are using any CAD software. In such cases you’ll definitely want a discrete graphics card.

A dedicated graphics card offers the following advantages (over the inbuilt graphics):

  1. Since all the video processing and rendering will be done by a separate processor (called the GPU or Graphical processing Unit), instead of the main motherboard CPU, the video is processed and rendered much faster – and – the overall system will run faster as the main CPU is now free to work on other aspects of computing jobs.
  2. Your RAM will be free for the operating system. It will be able to make use of all the installed RAM for itself as well as for your other software programs because the video card will have it’s own RAM to work with.
  3. Motherboards with integrated graphic circuitry, share a portion of the system RAM to use as the video memory needed by the inbuilt graphics circuitry, therefore the OS will not have the fullest RAM whenever you use graphic-intensive programs.
  4. Stand-alone video cards are made to support high-resolution monitors which are important for gaming, studio and CAD work.
  5. Most importantly, modern graphics cards support multiple monitors which are really useful for some (like me who is a chess coach and needs to share screen space) to use dual monitors with your PC.

Bottom line: If you plan to use your assembled computer merely for web browsing, emails, Microsoft Office suite of applications and other mundane tasks, I would not suggest you to buy a Graphic card. Save a few bucks by just buying a system with integrated graphics. But if you plan to play lots of games and/or run graphics intensive software or use dual monitors, you’ll be better-off buying a system with a dedicated graphics card.
