To make a long story short, I'm only able to play any games with the 66.93 drivers, all of the more recent ones make my card overheat to the point where I get random 5-10 second lockups constantly. My temps are as follows: with the 66.93 drivers, avg idle 52C, load 65c. With any of the more recent drivers, avg idle 76C, load 100C. Does anyone know what could be causing such a huge change in temperatures? I have an RMA number and am ready to send my card in for warranty service if it's defective, but I don't want to go without it for 2+ weeks unless it really is. Are there others here that have had similar issues, and if so how did you correct them?
