Ok they hit 750 on air, and thats getting to withing 5c of throttling, so i might have to settle for 725 as a 24/7 OC for the one im putting in the girlfriends system, the one in ther htpc i think i'll leave stock speeds till i upgrade to a 1080p TV then will see if it needs the extra boost of a overclock at that time. I got them both for $180.
Just though i would point out now that i actually own a few fermi's personally that people who complain about the stock cooler being loud are not kidding, not at all, they sound like jet engines. Although the blower style fan on my XFX 4890 i had a few years ago was almost as loud TBH.
FWIW it also almost doubled the framerate of the girlfriends computer in most games coming from a slightly overclocked 4870, even she noticed the difference right away and she is usually totally oblivious to computer performance. In her own words it was "way more smooth and less jerky", although she does try to play newer games with higher settings than the old tired Phenom II/4870 was up to, no matter how much i try and tell her not to run such high settings.
