With an Nvidia GTX 670 you are best off installing Big Sur.
The Kepler drivers were removed from Monterey during the beta testing phase. So Big Sur is the last release of macOS to support the Nvidia Kepler series of GPU's natively.
You may be able to update to an early version of Monterey using Chris1111's Kepler patches, but later versions don't work with the patches. Hence the recommendation that you install Big Sur.
The EFI's provided in this thread will work in Big Sur without too many edits.

- USBPorts.kext will not work with your motherboard, you will have to follow the guide to create your own.
- You will need to provide new SMBIOS data.
Those are the items I would change in order to boot Big Sur on your system.
If you want to create a custom USBPorts.kext using UtterDisbelief's guide (linked below) you may be better served installing macOS Catalina 10.15.7, as the

XhciPortLimit when Enabled, works in Catalina. It stopped working with Big Sur 11.3 or newer.
Important Update: June 2023 From Big Sur 11.3 on the built-in OpenCore XhciPortLimit quirk no-longer worked as described. This became a known "bug", though in reality it was Apple changing their internal code, making a simple "peek and poke" to keep it operating, a difficult task. However, with...

Creating the USBPorts.kext in Catalina is much easier than in one of the later versions of Big Sur.
That being the case, you would need to edit the

MinDate and
MinVersion entries in the config.plist to suit the APFS version used in Catalina.
Data required for the two entries is shown below.
