As far as I know, device drivers must be installed AFTER the card, so they may SEE the card for proper configuration
Over on the Windows side, I would...
UN-install the current graphic card device drivers
Turn off power
Remove old and install new card
Turn on power
When asked during startup, say I have a disc and want to use that instead of the default Windows drivver
No John, my detailed research indicated the Nvidia driver must be installed before the card installation. Folks that did it the other way complain that they had no monitoring when they booted. Lots of unhappy people were informed after the fact that the driver on MAC must be installed prior to the hardware installation and boot up of the new card. That much I am confident of. ;-)
Also does this Adobe page indicate the lastest and greatest drivers needed?
Ars Technica article
"The Quadro driver installation went as smoothly as you could expect given Apple's limitations. OS X requires drivers for cards to support drawing to the screen, so you have to install the driver for the card before you pop it into your system. This means that if you have to boot off of a 10.6 system CD, you will be headless unless you use another video card. It's been a problem for every video card that has been released without direct integration into the system, whether for ATI or NVIDIA parts for the past few years."

It was certainly current as of early last week, which is the last time I checked.
Thanks Todd. Thats good enough for me.
I loaded nVidia drivers prior to card swap, then loaded CUDA driver after nVidia card was in. All works correctly on my 2009 Mac Pro. I can now swap back and forth between my GTX 285 and ATI 5870 willy-nilly, and it works right every time when I reboot.
Actually I have done the install both ways and the Quadro Card in OSX gives basic video output long enough to get the driver in. I have not seen it not work either way and that is on both the 2009 and 2010 Mac Pro's. Also it says on the Nvidia website the Cuda install is after the driver.
