They run hot, and there's some guides out there to talk about not pushing them over 1.25 volts....

At stock voltage, I'm pegging 95C with terrific cooling on one card. in Crossfire, they run about the same, hot as ***.

I stopped trying to overclock it, you're not getting much more FPS out of it by pushing it.

after overclocking at 950-1150 at stock voltage,
max temp=79c(Weather is very hot in india)
i check also 1hour stabilty test....every thing is fine.
So, is that oc may help in increase fps???...
is there any way to increase fps without change any hardware?
OC and ???....

Without a change in hardware, no, not significantly.

check out the 670 FTW...I am eyeing picking up two of those in SLI to move on from my 6870 CF..

You will need a new power supply, that coolermaster has a short life.
