I'm currently using the 83.40 forceware drivers. Crappy deal about the unlocking the pipes, it's really a crapshoot if there damaged or not, 50/50. The good news for you though is the ability to OC the **** outta the card, thats if you have a XFX or EVG which have lifetime warrianties .So OC the **** out of the card and if it breaks send it back and get a new/refurbised one.
