My work computer has a Quadro FX 4800 and dual monitors, i want to add 2 additional monitors. 
  
I was wondering the pros and cons of putting a Geforce along side the Quadro. 
  
Geforce is cheaper then Quadro and all I need it for is the extra monitors. 
  
I run Solidworks, Autocad, and RasterCAD, but Solidworks is the program I am worried about as it requires the most strain on the computer and I don't want to limit it by adding the Geforce card to the computer. 
  
Any help would be appreciated
