@Amarysse, I have the same exact card and I thought it was because I overclocked it wrong, but everything is stable when I ran benchmarks. Good to know it's not the overclock or the gpu itself.

I do have a question for you Amarysse, have you done any S-ranks/Odin fights since you've gotten the card? I'm a little frustrated because my frames drop to 24-30 when my HD 7850 stayed at 40-60 but still extremely smooth. Could the drivers be affecting this or is it FFXIV sided? I would hate to think its the card itself.
