Guess 1.21v isn't that much voltage after all. How long have you been using 1.21v on your card? My max temps while gaming is 74c but mostly at 69c or 70c.
I have a 660 at 1.212 for about 6 mos. If anything it has gotten stronger with better drivers.
I also have a 670 at 1.212 (just got it) and a 670 at 1.175 had over a year (no need for voltage as its a strong overclocker).
I've seen no difference on any of them for degradation. I've heard of one guy's Zotac 670 getting degrading at 1.175 so I think it matters more about the general chip quality (individually) than anything else. If you're gonna get degradations you are going to see them even at 1.175, running at 1.212 is not going to be the reason you are getting degraded. It just might make the difference of a month or two in use. A bad chip is gonna degrade regardless of the 3% difference.Edited by battleaxe - 11/14/13 at 4:08am
