Is overclocking my i7 @ 4.5 Ghz doing anything for my gaming?

Is an overclock even necessary for my purposes?

I purchased a 2k rig a few weeks ago with the sole purpose of gaming. And by purchasing the 2600k I was eager to have it overclocked. (I know an i5 would have been just as good)

Not knowing what to do I flipped hit the TPU Switch on my ASUS motherboard. It did an auto overclock and get me the following results under heavy load.

I am running an i7 2600k and benching it with prime95..

Core speed - 4.4 MHz
Volts 1.376.V

Core Temps:
Core #0 Max 63 c
Core #1 Max 70 c
Core #2 Max 69 c
Core #3 Max 68 c

Lastly here are my parts:
Intel Core i7-2600K 3.4GHz Quad-Core Processor
Cooler Master Hyper 212 EVO 82.9 CFM Sleeve Bearing CPU Cooler
Asus P8Z68-V PRO/GEN3 ATX LGA1155 Motherboard
Corsair Vengeance 8GB (2 x 4GB) DDR3-1600 Memory
Western Digital Caviar Black 500GB 3.5" 7200RPM Internal Hard Drive
Crucial M4 128GB 2.5" Solid State Disk
Gigabyte Radeon HD 7970 3GB Video Card
Cooler Master HAF X ATX Full Tower Case
Corsair 850W ATX12V / EPS12V Power Supply
Asus DRW-24B1ST/BLK/B/AS DVD/CD Writer

Again is the overclock even needed at this point?

I have constatly 70+FPS on ultra details even with HT on. It does make a difference in gameplay but when I have 70+FPS -5 is not a tragedy and I don't want to change it every computer start up. But for other people when you have for example i7 2600 + GTX560 or HD6850 a +5 gain can be a lot.

Overclocking cpu helps in cpu bottlenecked games or situations where your graphics cards are powerful enough that framerates are being limited by the cpu's ability to process what the gpu's are doing. I.E. heaps of gpu horsepower needs cpu horsepower. In most situations the gains aren't usually that impressive, but still its never going to slow down your games only possibly improve them an overclock of 4.4 is low enough that you wont(likely) hurt your cpu anyways as long as temps are fine, and a hyper 212 evo is more then enough for that overclock.
