    I thought I would start a post for people to share their 680MX overclock settings and benchmarks. I know this is something I was really looking for, and couldn't find, when I was looking to buy my iMac.

    Overclocking this thing is messed up, I have tried for many months now and no matter how you put it, there is no way to go over 999mhz.

    I kept it way cool and even disabled turbo but somehow something stops it from going over 999mhz. As soon as I overclock and put it for a test; it restarts automatically lol.

    I can almost play all the games at 60 fps at 1440p but there are a few exceptions like Crysis 3 that just won't let you do it, however 1080p works fine. Planetside 2 won't let you hit 60 either unless you lower something but trying maxed out won't work.
