Hello. I have a Dell Inspiron 15R Intel Core i5 laptop and I need to upgrade my graphics card so that i can use Revit on it. I was thinkin of Nvidia QUadro K1000M or Nvidia QUadro K5000. Are these compatibile with my computer or if not what high powered graphics cards can I use with my operating system. The laptop currently works off Windows VIsta. Many Thanks
