I am given to understand thats the throttling point - not that it's full throttling at those temps, it's progressive as temps increase.
Of course you can run ur Nvidia card right upto 120degrees Celsius (if you want to??) but it's in everyone best interest to run as cool as possible.
They are only following Intel and AMD using throttling as a way of controlling temps.
I dont know enuff about ATI modern stuff but my 8500 overheated real quick and then crashed, it had no throttling.
Was there a point of overclock on the X800 where you got your best Benching score? and if that was lower than your max overclock it suggests that ATI had throttling too (I presume they do)?
I always try and play things 'devils advocoate' and look at what other manufactures do to protect the consumer, then consider the consqequencies of not doing something.
Thats not to say I dont agree with you (maybe not to the same boiling point you have expressed) coz I do, I think Nvidia are more conservative when it comes to these things (appeals to a more global market of non overclockers and shuttle users) and I believe they put reliabilty at stock above all other considerations.
Of course it's also a good reason to use Arctic Rev5 or ORB cooler or similar to keep those temps to a more 'conservative' level when overclocked and prevent throttling when benching.
My Arctic cooler kept my GT's at 68 degrees fully overclocked 2hrs+ of unreal tournament, the 7800 runs cooler than the GT so temps should be lower.
It's like the Intel and AMD heatsinks for their CPU's, they're okay but as an overclocker you'll look for a better solution (EVO33 anyone?).
