The GTX 770 is going to be a much better option for these reasons:
1) The GTX 770 is a higher performing card overall, and comes with the benefits of the Nvidia ecosystem: Adaptive VSync, TXAA, FXAA, Monitor overclocking, Shadowplay, PhysX, Geforce Experience, better SLI game performance, etc.
2) Your games list features several PhysX games that will require the GTX 770 in order to successfully enable all the graphics settings. Also, in Skyrim, only Nvidia cards allow you to enable Ambient Occlusion which significantly affects the quality of almost all the in-game visuals.
3) The GTX 770 overclocks itself with Turbo Boost 2.0, so it's a good option for someone like you who does not intend to overclock manually.
