Ok I'm going to answer this myself.
After further xshooting, I removed the entire video driver files for the GX760 out of the driver database and rebuilt the database.
Reimaged the computer with provisioning, and it went completely through except after logging into the desktop, in device manager, there was no video driver, back to square one.
I went into the HII manager and selected the GX760 and video device, searched for a driver and found one, then assigned it that driver. When back and imaged the computer and the video driver was installed.
