But yeah, I took GTA IV for a spin, and damn that's a big difference. I was getting 20- fps with default settings, and now I'm getting 30+ fps with medium textures and everything else to the max! With graphical enhancement mods! Awesome!
It always feels good to karate-chop a bottleneck into oblivion.
EDIT: I was thinking of trying a mild overclock, but neither ntune or the BIOS will let me change the FSB; when I change it through the BIOS no difference shows up with CoreTemp.
