title: Using a GPU both as video card and GPGPU
body: <p>Where I work, we do a lot of numerical computations and we are considering buying workstations with NVIDIA video cards because of CUDA (to work with TensorFlow and Theano).</p>
  
  <p>My question is: should these computers come with another video card to handle the display and free the NVIDIA for the GPGPU?</p>
  
  <p>I would appreciate if anyone knows of hard data on using a video card for display and GPGPU at the same time.</p>
