A large variety of users use Nvidia. If the driver is fairly recent you should be fine.
If your having steam compositor errors; a reinstall of steamvr might fix it.

Support has an awesome tool to help get you running. Skype with Teamview. Due to different timezones may need to find a time that works best.
If you could post your system specs (cpu/ram gpu windows ver)
First 3 serial numbers & firmware version.
Also if you know the steam error code this will help as well.
