Does anyone know how to go about flashing a Gigabyte gtx 560 for the Mac pro? I wanna use the boot screen and not after using opencore.

Sure?
This is a very old card, based on Fermi-architecture and has no metal-support. In my opinion, leave it as is. Also most older cards have a small flash-memory to store the complete rom, soldering required to change the memory.
