lenovo b50-50 win. 8.1 drivers

I waa install win 8.1 64 bit for lenovo b50-50(i5 core) with 920m nvidia graphic card. There's no drivers for this model and win 8.1(both 32 and 64 bits) at lenovo web-site, only for win. 10 and win 7.

Of course I'll download and install the nvidia graphic card drivers from nvidia site, but what about all the soft from lenovo web-site? Should I install the win 7 drivers to my win 8.1 64bit, or better go with win 10 drivers, or what do you think will be best in this case?

Thanks
