Ok, so just recently went from a 460 768mb to the 660 2gb (I know I need to update my q6600, bare with me...) I seem to be having issues. No BSOD or driver errors or anything, but every now and then my screen will just go back to desktop, no error, nothing, but I must force close the game. Games tested so far have been BF3, Fear 3, and GRFW. Now I have underclocked the card down about 40 mhz (i think anyway, not too sure how this whole new boost thing works) and its much more stable. Voltage is 1 on load and 1.117 on boost. I know I could RMA the card and (most likely) the issues would go away, but would it be worth it for 40mhz especially since the card seems well above reference clocks anyway? I'm not really sure how to proceed with this, either RMA the card, bump up the voltage, or just bring the card closer to reference clocks. This whole Kepler thing is kind of confusing me, and the way that both Afterburner and Precision changed doesn't help. Can anyone help a newb shed some light on either the way the card/programs work or what I should do about the card? With the card underclocked just a bit I still am blown away by the performance. Nothing can seem to slow it down and since I'm not much of a AA nut and a max res of 144x900 (cheaper monitor) I don't really think I'll be stressing it much more than I am.
