Help Me Choose: Video Card

Whether you’re gaming, watching DVDs or editing video on your Dell™ desktop, the quality of the graphics you experience is only as good as your video card.

Along with the display, the video card affects the number of colors available, contrast, resolution and overall performance.

How Video Cards Work
Discrete video cards can provide better performance, as compared to integrated video cards. Discrete video cards are separate from the motherboard and include a specialized graphics processing unit (GPU). Because of their onboard GPU, discrete video cards don’t have to share the CPU with other programs.

Discrete video cards include memory of their own, measured in gigabytes (GB). Graphics memory is used by the GPU to accelerate graphics performance, store textures using game graphics, and make gaming, movies and other entertainment intensely realistic. High-performance graphics cards require a significant amount of graphics memory.

Integrated video cards are built in to the system motherboard, and use the system’s processor (CPU) and memory to create graphics. Integrated video cards are fine for applications such as word processing and email, and for the internet, but not great for gaming or other graphics-intensive applications.

While integrated video cards can process some complex graphics such as 3D images, they have to share the CPU and memory with other programs. If the CPU and memory are overloaded or busy processing other information, integrated video cards can really slow down the graphics.

 

The system you are configuring may or may not include all of the options listed here.

If you want...Choose...
To tackle complex graphics, applications and gaming, a discrete video card can handle all the applications an integrated card can handle, plus:
  • Complex presentations
  • Graphics design
  • Financial analysis
  • High-resolution video
  • Video conferences
  • Dual monitor setup
A single discrete video card
An entry-level solution for typical office productivity applications, internet use, relatively small digital images, low-resolution video, simple games and other relatively undemanding applications, integrated video cards are generally acceptable for:
  • Word processing
  • Instant messaging
  • Small presentations
  • Spreadsheets
