Same here - I'm getting to the stage where I'll take anything as long as it's quieter/ cooler than my 480.
I side stepped from my overclocked 480 to my overclocked 660 (non TI) because the heat and noise was just getting annoying.
The 660 I have now performs very slightly better than the 480, but I wouldn't say it's enough to notice, so the 760 will be a noticable upgrade
