Wishing to upgrade my dual Xeon system for one last time (dual core...who
needs it:-) I thought I would swap out my trusty Quadro 980XGL in exchange
for a Gainward BLISS 7800GS+ 512MB

How best to install it?

Can I just uninstall the Quadro card from Device Manager, remove it & insert
the new card and let the latest NVIDIA drivers (84.26) identify and install
the BLISS?

Will these fully support the Gainward card?
