Free games typically aren't that demanding.  Show us what your current build is and what games you intend to play.

Lets see the rest of your build, I'm confident I will be able to cut costs in other areas to help make more money for the GTX 780.  I vote for the 780 because it is an incredible, incredible card that will last you for a very long time.  I do the exact same thing with my 780, one very nice IPS panel monitor for my games, and one older monitor which is not as nice for my media and web browsing while gaming.  The 780 handles both even under the highest settings on the most demanding games.
