Is it worth using OCLP on the iMac 2013 27” 32gbRAM/ Intel i7 / Nvidia GTX 775M 2gb?

I ask if it is worth putting it on the latest version of MacOS (not the Tahoe) for the sake of video quality, video usage, as I have experiences on a MacBook that is much weaker than this iMac, which loses a lot of graphics performance, some things are slower, FPS drops in some applications.

So, in the case of this iMac, can it be used safely?
