An i7 at a lower clock would be faster than an i5 at a higher clock because i7s have hyperthreading while i5 only have turbo boost. An FX 8150 @4.8GHz shits all over a stock i7, but again, the i7 is at stock
Hyperthreading only offers an advantage if the application in question supports multiple threads. The vast majority do not, certainly not upwards of 8 threads. Many games are only optimized for two cores. Developers cater to the lowest common denominator.
As for overclocking, Bulldozer at 4.8 GHz performs worse than an i5-2500 at stock when gaming, and only offers equivalent performance when video editing, a highly parallel task. The fact of the matter is that clock-for-clock Bulldozer is not impressive. Overclocking would only be beneficial to Bulldozer if it were capable of substantially higher clocks than Sandy Bridge, which it isn't. My 2700K runs 4.8 GHz smoothly.
An FX 8150 @ 4.8 GHz is overall (less than) equivalent to a Core i5-2500 @ 3.3 GHz.
Incorrect, many games of 2012 require 4 cores for "acceptable" play. I can't play BF3 on a dual core and get 30fps on medium, which is unsubstantial. Anything higher than an i5 for gaming is overkill imho. i7 is really for video editing, streaming, things that as you stated support multiple threads(as Sony Vegas did not, they updated a few months back to support it, as have a couple games). I've seen people stream BF3 just fine on an i5 anyways.
