I'd say temps in the high 40s to low 50s with near silent operation.
My aircooled 470 has a 70mm fan from an AMD heatsink and one of the stock 80mm fans from the twin frozr cooler because the other stock fan broke, it's getting the air from my watercooled card's rad and they're both overclocked.
Both cards and my CPU have been folding 24/7 for about five days at somewhere near a 21C ambient temperature and it's topped out at 63C at 60% fan with the AMD fan at full speed.
My card needs over 200W to function so that cooler should cool yours with absolutely no problems.
Edit: At stock speed when I had two fans blowing fresh air straight at my card and not through the radiator at my card I was getting a max temp of 53-54 so that's why I say high 40s is what I'd expect you to get. If you've got good airflow in your case that is.
