Yes, I think I will be lapping the cpu as well, and applying better paste to the internal heatsink. I've always used Liquid Ultra cooling paste, pure metal, but can be harmful. But, always achieved about 3-5 degrees lower than the best cooling paste (IC Diamond for example). I have not yet tried it on the internal heatsink yet, but I might give that a go. I have the Noctua NH-D14 heatsink. Which one do you have?
EDIT: Going a little bit off-topic I realise..
But, on topic, I think temps also play a big role. I've managed to lower my GPU temps about 13-14 degrees C on OC, compared to stock (no OC). That's a huge difference. But it seems as if my card has some sort of temperature wall of 70 degrees C, above that, OC becomes significantly more unstable. So, with all modifications, I hit a max of 65 degrees on 1.212v when playing the most gpu intensive games. Had to do a series of mods to my gpu and case airflow. But it seems to help. Usually with V-sync on, temps stay below 60 degrees when playing games like AC4 or Tomb Raider. Of course no high AA settings, preferably off, I think that looks better, more crisp than with any type of AA (at 1440p that is). But that's a matter of taste.
