A 760 will allow you to play high/ultra settings at 1080p in almost any game (assuming ~40 fps is acceptable). I would bet you could get absolutely fine performance at 1366x768 with a weaker GPU. I might even go as far as to say a 760 would be going to waste at that resolution.
I would recommend an R7 265 or even the 260x. The nvidia 750 ti is basically the same performance as the 260x, just more power efficient.
If you want to spend the money and get the 760, I would suggest getting a 1080p monitor to take advantage of that $250 card.
