When you install Windows, it automatically installs all of the drivers necessary for most devices. However, there are a few exceptions. I don't see any of those exceptions in your build. The only one you might run into a problem with is the USB 3.0 driver for the motherboard. You can get that from the Gigabyte website: GA-Z68A-D3H-B3 (rev. 1.3)
. Also, if you have a Wireless USB Network adaptor, windows may not include a compatible driver for that so you will have to download and install it after windows is installed (or use the Driver CD that comes with it).
