I have previously tried doing it to my msi gtx560 two years ago and how stupid am I , I baked the card upside down, .. capacitors facing down. after baking I notice all the caps falls off , so please be aware of this if you guys want to try. haha , then a month  ago my bros gtx 460 got artifact, I baked it the right way and to my surprise it really works. hopefully It will last for another year or so.
