The GTX 770 is recommended mostly for the Mac Pro 3,1. Also works great in Mac Pro 4,1 and 5,1. Very rare reference model!
It uses same drivers as GTX680 and that's why it has native support under any macOS version. You may choose to use the Web Drivers, or simply use the built in Apple ones. Works great under macOS Mojave, Catalina, Monterey (after installing GeForce Kepler Patcher) and Ventura/Sonoma/Sequoia (via OpenCore Legacy Patcher).
