I went from a 2600K to the 3930K. 64-player multiplayer BF3 went from 60fps minimums to 100fps minimums. Definitely not trolling, read this: http://chipreviews.com/main-feature/main-news/frostbite-2s-limit-6-core-performance-in-battlefield-3/5/
Also, I absolutely agree with you about the iMac, that's what I said as well. It destroys the BenQ in every way except gaming.
Nobody needs 100+ fps, it's just a lot smoother and I prefer it. Plus you don't get the lightboost benefit under 100fps.
Hmmm interesting
It's 2011 after all ;D
