I did test out a bunch of my games last night and the results are basically this:
I can run all of my games at 50-70 fps with all settings in game and in CCC completely maxed out at 1920x1080.
BUT there's two things...
I absolutely can't touch super-sample anti-aliasing. I must keep it set to multi sample or adaptive multi sample in my CCC because the frame rate cripples extremely quick once I try using SSAA
And the other thing is Metro 2033. I can run it on the highest settings but I have to keep tesselation off and have to keep "advanced DOF" off. Also, I cannot use in game MSAA. If i have my CCC set to override application settings I can use all the MSAA I want, but the in-game MSAA just bogs it all down.
I didn't know what to use to log fan temperature, but I frequently turned off my speakers and listened, comparing the noise level to that of what I'd heard when doing the furmark test. In short, none of my games caused the fan be even half as noisy as what it was in the furmark test. Granted I don't have BF3 or Crysis to really put some stress on it, but Metro is a considerable benchmarking game.
One thing I noted is that Skyrim really hates this card for some reason. There is more Z-Fighting than you can shake a stick at in this game (yet Elder Scrolls 4, Fallout 3 and New Vegas barely have any???), and no matter how I tinker with the settings, I can't get the clouds and mountains to look normal}. Oh and did I mention random trees flickering in and out of existence in the middle of the sky? GRRRRRR! It looked beautiful on the 6770!
I will look into a better cooling solution though, as I don't want it to get excessively hot in there.
