BF3 indeed uses all cores including the fake cores, so does SWTOR.

Have a look at the FPS & cpu usage. Might give you a view. Well I rather think a 2600k will bottleneck a configuration 4x gtx 680 (1250MHz on gpu & 6500 on VRAM) in resolutions like 3 monitors of 2560x1600.
As you can look in the screenshots, the i5 will in that situation running around let's say 60-70% because it's 30% less powerful.
Also it depends on game though. Something like unigine heaven which is just insanely written, my cpu only sits around 5-10% while everything maximized with a gtx 680 (1300MHz core, 7600MHz VRAM @ stock volts/power)
Having a look into the future with much heavier games & better graphics cards, the i7 will last longer than the i5 IF the game makes USE of HT.
Personally, I haven't noticed any fps gain with having HT enabled or disabled during BF3 @ 1080p ultra. In that situation the i5 does his job perfect while the i7 does it job also perfect.
Some games are only making use of 2 main threads like WoW and overclocking helps there a lot. If you don't mind the voltages, the i5 can be pushed more than an i7 just simply because the i5 will run 10-12° cooler than the i7. HT makes your cpu running hotter, yes.
beyond 4.6 you dont notice as much of an improvement, and really need a benchmark to show results
HT has its advantages when it comes to multi tasking and core count based programs, but im not aware of any game that can seriously take advantage of HT or 6 core CPUs, which is why the i5 is always recommended for a gaming pc, while its not the best performance-per-dollar CPU, it reaches the top of gaming performance and anything more expensive will not give better results worth the extra cost

As we know that core0, core2, core 4, core 6 are psychical cores and all the others are the fake cores which I disabled through task manager for BF3. If I disable HT in bios which would make sense my Total CPU usage will be higher.
You won't see any performance gain @ 1080p ultra with an i5 or an i7 in any game.
also 120hz for BF3 might have a need for it .
why changed the pic's? (first ones you linked were you standing between containers @canals map)
ofc it matters if you got 64 people blasting each other to bits with every explosion being rendered in the highest settings.
the reason i mentioned a 120hz screen was that HT might provide the push needed to hit the 120fps mark there compared to an i5 which might just be +-20% frames off easy.

I didn't use halfscreen because I wanted to show the gadgets though.
Vsync was disabled so in both screens. Screens are in 1080p so is my resolution.
What does a 120 hz monitor matter now? I didnt use Vsync and I don't have a 120hz monitor
