i 2nd that. i spent almost $715 when the overclocked 8800 gtxs came out only to get pissed that every 5 minutes i would get a BSOD since the drivers were crap. And even so many months after launch, the drivers were still crap. 2 weeks ago when i updated to the new 177.xx they screwed everything up and started BSOD all the time. And so far, i haven't gotten any BSOD's from my 4870 x2.
Same experience here. So far this has been my most stable video card since my 7950gt!
