Please notes:

1.QE does not test Telsa card since we do not get this card from Nvidia.
2. "NVIDIA GPU Device Assignment Red Hat Enterprise Linux 7.0 Beta supports device assignment of NVIDIA professional series graphics devices (GRID and 
Quadro) as a secondary graphics device to emulated VGA.",According to last comment in bz987658's Doc Text, Telsa is not mentioned. 
3. QE will consider test telas card as well if we get the card from nvidia timely(before snapshot10). Free to update your comment as well.
