On-board video.

Specs: Windows Vista

just wanted to know if an on-board video card takes away a portion of your CPU (same way it does with RAM) if you don't have a PCI video card?

In a nutshell, onboard usually just uses system memory. The game or application dictates how much the gpu and cpu are used.

Depends on the chipset. If the onboard video doesn't support certain API calls like T&L in hardware (Intel GMA950 and earlier), then the CPU would be used to handle T&L calculations.

However, modern integrated video solutions support all D3D and OpenGL API calls in hardware, so CPU horsepower is no longer a concern.

Forget about PCI video if your system has GMA X3500, GeForce 8200, or Radeon 3100 integrated graphics or newer. A PCI video card may actually slow you down, since modern PCI-Express chipsets aren't as well-tuned for standard PCI performance as the older PCI/AGP chipsets were.
