Why upgrade drivers?
There are two main reasons to upgrade drivers:

1. Compatibility
Compatibility issues are the #1 problem solved by updating a driver. For instance, certain software may not run correctly due to the way an outdated driver displays on-screen information. This problem can be solved with a new video driver or with an updated software version.

2. New Technology
Some peripherals, such as inkjet printers, rely on processor computing power for productivity. Other peripherals, such as graphics accelerator cards, integrate dedicated chips for productivity. An up-to-date driver optimizes the communication speed and task sharing between your processor and peripheral. This can increase your system performance by up to 50%.
