I am loading 2 models into gazebo-2 and find that the ratio of real-time is never better than 0.5 and is typically 0.2. currently using => Geforce GTX 750Ti 2-slot PCI-e 4GB. My processor is an Intel-i7 with 8GB of RAM. What type of graphics card is required to run at full speed?

what model are you using? those seems like pretty good specs to me

You can increase the simulation speed by changing the physics values in your world.sdf:

For example, I use:

<physics type="ode">

This way you can simulate a larger time step per iteration and thus increase the real time factor.

Now that I updated the Nvida driver to the latest version, I see a ratio of only 0.17 for the tutorial with the PR2 model and the gas station. I am guessing that there must be a check-box somewhere to tell gazebo to use the stream processors on this card.
