Quietest! gtx 780,780ti cooler.

guys im looking to jump to the green team for my next card currently there are a few brands that are using there own cooling solutions. what i wanna know is which is the quietest at 75% fanspeed+. i have a 5870 with an arcticcool after market cooler and its near silent. so quiet in fact i have a hard time hearing it over my be-quiet cpu fans which also make minimal noise.

as you can guess i want to replace like for like (quiet for quiet), but this time forgo having to buy a none standard cooler.
i hear saphire do particularly well at quiet coolers. is there a comparable model to there latest r9 290 offering from an nvidia manufacturer.

so suggestions, links and opinions plz, especially from owners of the above cards.
 
well after having a listen to them they all seem louder than my 5870, i really was hoping for something that was gonna be at least as quite...
even when mine is up full you cant even hear the wind noise and thats at 2000 rpm.
the msi 780 twin frozer isnt absolutely terrible as it sounds like its still quieter than my case fans.(not loud but are audible).
but like i say i was hoping for even better, then again it seems maybe im hoping for to much :(
