I haven't seen any reports of Gigabyte gaming OC crashing due to the boosting issues, no matter how hard I searched online. On the contrary, including this thread, other users using the card have said they have experienced no issues. However it may be that not enough have got their hands on them yet to get an idea as to whether this card has any issues.
My particular issue I believe is unrelated to this whole boosting and crashing issue as I have tried under-clocking and reducing power and was still experiencing my stuttering problem at lower clocks. Still, this whole thing makes me want to wait and see what AMD offer.
