If you are running Windows 8.1 64-bit these drivers should work for you. I've been using them without any concern for 1 1/2 months now.
The best option is to slipstream them into your image (install.wim) thusly:
DISM /Mount-Wim /\install.wim /Index:1 /MountDir:
Index:1 is Windows 8.1 Pro, Index:2 is Windows 8.1. Extract the attached archive to your HDD (one folder ie: "Drivers") and slipstream:
DISM /Image: /Add-Driver /Driver: /Recurse
then:
DISM /Cleanup-Wim
Finally:
DISM /Unmount-Wim /MountDir: /commit
Install Windows 8.1 Assessment and Deployment Kit (not completely necessary, but, creates a new cat file for your modified wim); only the Deployment tools and Windows PE Enviornment:

You can also create an answer file (Autounattend.xml) from here-the help files are very good and will guide you well.
Copy your new wim to your installation media and bob's you're uncle;)
These drivers are all the latest from Intel's/Asus website and are WHQL. I used the Intel® Management Engine Interface (Intel® MEI) from ASUS download culled after running the exe during my first install on a VM.
The 32-bit files are the same just not "x64" appended to the file name within the downloaded driver archive. (zip file, not exe).
The other more laborious method is to point Device manager in Safe Mode after Windows installation to your extracted driver folder, view Devices by Connection and individually update all that will in "PCI bus" and "PCI Express Root Complex"-reboot normally when done.
I've had no driver issues at all-24/7-and I push my PC pretty hard gaming so.....if you want give it a try.
