pls suggest proper drivers to improve GPU Load

Hey Guys…could anyone please help me to find drivers for 64bit windows for Quadro k2000 Graphics card.
when i installed any drivers provided on the site my system GPU Load is showing not more than 3 percent usage.
by the way i am using for after effects.

Did you follow the Adobe After Effects guidance on GPU usage?
