How to add Nvidia drivers... (Noob Question)

Sorry to ask a noob question. I searched a lot but got nothing working.

I successfully created the latest Win8.1SEx64 iso and everything looks nice and works well, except the choice of video resolution.
Can someone show me the way to integrate some Nvidia drivers when using Winbuilder. ?
I have a 16/9 display monitor Asus VE247  recognized by Win8.1SE , but I can only use few 4/3 resolutions (1024x768 - 1280x1024 and 800x600).  Drivers are basic MS from setup.
Quickres show the same.
Is there a way to put some basic Nvidia drivers for my Nvidia 660 Display adapter ? (Not to play games..  )
Excuse my ignorance and my terrible English.

Try this:
Use Drivermax (free) to "capture" and save your Nvidia drivers in this folder:
C:\Win8.1SE_PE\Workbench\Common\drivers_x64\drivermax\Nvidia

In winbuilder enable Driver Integration script

Thanks you Oscar,
I will do that and make a new build.
This project is awesome
