gtx 680 sli which card should go on top?

Hi I am writing this thread because I need some advice. I have a reference design gtx 680 and I just bought a second zotac for sli but went with the zotac amp!edition because it was cheaper than a reference card. Any advice which card I should put on top? I know the reference design will push heat out the back and the amp edition will most likely push air back into my case based on the look of the cooler. Please let me know what you think, and if its not to much trouble a brief explanation would be great.

  1. I would suggest the zotac go on the bottom and reference on top, but really it factors of your case and the airflow already inside your case need to take into effect as well.
  2. The case is very large and has great airflow. What way would you swing knowing this?
    I just ran the heaven benchmark and it ramped up both cards into the low 80's after just one round. I know what isn't extreme but its not ideal either

    For a large case and great airflow, you're not going to see much of a difference, if one at all, either way you set it, at least with with the acx cooler on the bottom the heat from that card won't be blowing onto the back of the reference card.

    Running a benchmark though 80 isn't too bad, since that's stressing it to the max. Real world applications though, most likely, won't be pushing it as high. Honestly, though, as long as you're below 90 degrees, you're in a perfectly acceptable range, especially if the cards are OCed.
