I have not been able to find a certified drivers for the  NVIDIA Quadro FX 5600 I have installed on my workstation.  The version of driver I have is 8.15.11.8593.  This seems to be newer than any I have found for SW.  But I still have refeaseh issues and my WS is really doggy.  I have just recently reformatted and installed a fresh Window 7 OS on my WS.

Any suggestions would be helpful.
