Today, I was cleaning my workspace and desk top for dust. I decided to work on the cable management of my desktop and I noticed the sticker from my 6870 was coming off. Not a big deal, I suspect heat is the cause. But then I looked at the pcb of the card and saw it looked oxidized in some areas. I did a quick google search and saw only one related thread and they said its not a big deal if its still working. Before its shipped out its bathed in a solution which may contribute it. I was wondering what you guys think about it, I'm not very nervous about it but I am concerned. For the record I've done some very mild over clocking, but never kept the values due to artifacts, so yeah...
