Running CF 7950 @ 1440p on Ultra. Noticed high temps as well (not as crazy as OP's). Primary card hit 78 @ 100% load. Secondary hit 64 @ 100% load. Been awhile since I saws temps on the primary that high.. maybe Metro 2033?
I also have 7950 CF and same resolution (1440p), all details maxed. Also seeing very high GPU temp, up to 76c-77c. The GPU usage is 99% / 65%. And yes, Metro and BF4 is basically where I see those temps.
I use AFR for eocapp.exe otherwise the performance isn't smooth (choppy with either "default" or disabled" CF setting for the exe).
