Mac Pro 2007 Video Card No Display

My video card went bad on my late 2007 Mac Pro. I bought the Quadro FX4500, which Apple listed as a compatible video card for my machine. I made sure to get the Mac version of the card. However I've put my card in my machine, attached the power cable, I hear a boot sound, but no display ever comes up. Does anyone have any ideas?

Mac Pro, OS X Mavericks (10.9.5)

Since you are running greater than Lion on a 2006-2007 Mac pro you must be running a hacked system.

The Quadro FX4500 requires a 32 bit EFI but the 2008 and and later, and the hack gets a 64 bit EFI

Oh wait. You actually just reminded me. It is a 2008. Sorry I got my years confused.

The 2008 and later Mac Pros have 64 bit EFI but the card only works with 32 bit EFI.
