I was able to run GTX 970 and old Apple GT 120 (for boot screen) under Win 7 up to 340.52 Windows driver. I was unable to update to GeForce 344.11 Windows driver as support for GeForce 9 series (Apple GT 120) is dropped. I can run GTX 970 and Apple GT 120 under Yosemite fine without any problem (Thank you Nvidia for 343.01.01f01 web driver). Unfortunately, I am unable to run both GTX 970 and Apple GT 120 under Win 7 as GTX 970 requires at least 344.11 or 344.16 driver which no longer supports GT 120. Unlike Old XP which supported two separate drivers for two separate video cards, Win 7 wants to assign one driver for both video cards. Now it seems that I have to either ditch GT 120 and forgo boot screen. Or get Apple AMD EFI card just for boot screen. Am I missing simple solution?
