north and south bridge of a motherboard
If i am not mistaken i believe the Video Card is run off of the North Bridge of the motherboard.
Is a chip that implements the "slower" capabilities of the motherboard in a northbridge/southbridge chipset computer architecture.
Primary PCIe slot
The north bridge controls pci, pci express, agp, and other cards, and south bridge controls the drives and onboard devices.
North bridge connects the processor, memory and video card. South bridge connects all the peripherals whether it is connected using USB, ISA, and PCI connector. Note. South Bridge is also connected to north bridge
the sandy bridge chipset uses a single chipset housing
Input Device (mouse) sent through the motherboard -> Processor -> RAM -> South Bridge -> North Bridge -> Graphic interface (video card)
In computing, the motherboard is the main circuit in your computer. It houses all of your computer's hardware components and creates a bridge for them to be connected.
That would be the motherboard. The motherboard controls and holds all components that tells the computer what to do. So components like CPU, HDD, SSD, South/North bridge etc.
