All the recommendations and I don't think anyone knows what mike has for a CPU.
I can tell you this Mike, I have a GTX 780 made by EVGA and it's been a solid performer for over a year now.
I did need to overclock my i53570k to 4ghz to feed the thing smoothly and could probably do 4.2ghz. I decided to tone it down a bit for CPU longevity.
It wasn't going to burn up at 4ghz but every cycle in an electronic part brings it one step closer to death.
A super card won't do you right, if the CPU and Mobo can't feed it.
A caveat about the newer GTX970/980s is this. Independent testing is showing them to put out higher FPS and use way less power then the older generations of cards, but it was discovered that they are noticeably weaker at AA than the older 700 series cards (last two digits in model number being the same). The testers have been puzzled by that.
Just for kicks I found a comparison between your old card and the GTX750ti...

A notable improvement is the GTX970.
