Quadro 4000 Driver Failure-DAILY

All,

     Is there a graphics card and driver better than the Quadro 4000? I have a T7500, Windows 7 running Solidworks 2012 x64, and my graphics driver is failing almost, if not daily. Usually it is around 3pm, through the work day so I was thinking of overheating and I put a fan under my desk.But, it just happened again at 7:30am when my system was shut down all night. I need a reliable graphics card so I can continue to work and not lose data.
