650Ti, if it's a real one with a GK106-220-A1, is a Kepler Generation GPU and NVIDIA web drivers supports it only up to 10.13.6 while Apple has it's own drivers that extend support to Mojave and Catalina.
750Ti is a Maxwell one and supports ends with 10.13.6. Apple don't support Maxwell GPUs since no Mac ever had one.
