Looking for 660 ti overclocking help

furmark creates too much heat on the card and is sort of bad for it, you really dont need to overclock the 660ti its powerful enough, just do a 15-20% overclock on it, try not to mess with the voltage either. it probably down clocks so much in furmark because the card is resetting its overclock because it cant handle that much of an oc. the difference is give or take 5 fps and my gtx 580 runs skyrim on max settings with 2k textures in the 50-60 fps range 24/7. just leave the card alone with a small overclock you're only gonna get 1-3 more fps by pushing for that highest overclock which is unecessary
