It looks like the GTX 760 will give you about 35% more performance. In terms of value, the GTX 760 might also come with a couple free games, including Assassin's Creed IV. You might also find some value in the unique Nvidia technologies that will allow you to play around with PhysX, Adaptive VSync, Shadowplay, Geforce Experience, and some of the new quality settings like FXAA, TXAA, HBAO+. In general, if you can afford it, its always a good idea to bump up your performance from an entry level card to an upper/mid-level card.
