It's likely just part of a normal cycle. One's up, then makes a few blunders, and someone else (ATI in this case), is ready to fill in.I don't trust Nvidia after my 8800 GT died and I became aware of the general high failiure rate. Add it to the problems in the laptops with the mobile GPUs and Nvidia just seems flaky ATM.
I'd like them to recover though...Competition is good for us as consumers.
