First GPU for current setup. NVIDIA 710 would do the trick for how many years?

Hello! I’m trying to add a gpu to my setup (Clover in BigSur), and the most cheap alternative seems to be de gt710. Any of you know if it works with dual monitor? And how many years may still be supported by apple? 🤔

Current setup: i7 8700k, 32gb RAM, Z370 Aorus Gaming 7, WD Blue 1tb ssd.
