Graphics card for 3 monitor setup: 4K + 2x HD monitors

What would be a good graphics card to run SolidWorks (currently on 2014 but will upgrade to 2016 soon) on a Win 7 x64 16GB RAM system that has two HD 24" monitors and one 4K 28" monitor?  I currently have a Nividia Quattro K2000 but constantly getting crashes with the 'Your hardware configuration does not meet minimum specifications needed to run the application. The application must close.'   I have installed the latest driver.  Something that won't give the IT guys a heart attack would be good.
