Help decide to OC or not + how high OC reccomended?

Hello! I want to OC my CPU! I have no idea about anything related to overclocking so any info will be happily taken.

Question: what risks do i take other than chance of CPU breaking and void of warranty?

Question: How high do you reccomend i OC depending on CPU cooler and what i do? Anything else to think about i missed?

Intro:

I just watched https://www.youtube.com/watch?v=MTEQrFHFp3M (Xigmatek Aquila microATX Case Overview, tek syndicate) and i decided im going to make this my new case.

But before i can do that - id like to burn out my cpu/mobo seeing as im changing/upgrading those anyway for the new case. I will not OC my gfx card yet seeing as i can use that in my later build. 

Currently everything i have is stock specs. Everything is 2 years old except for gfx card which is 6 months old.

 

Computer specs:

Motherboard: MSI p67A-GD80

Processor: i7 2600k

CPU cooler: closed watercooler: Antec Kuhler H20 920

Graphics card: Sapphire radeon HD7970

RAM: 16GB Corsiar vengeance

Powersupply: Corsair TX V2 850W

 

What i do: 

- i have 3 monitors so i usualy play CoD/bf4/hearthstone/planetside2 on the middle screen. (as high settings will go while keeping 50+ preferably 60+ fps).

i watch videos from youtube in fullscreen 1080p on my right screen.

And i usualy livestream with OBS/filming for video to edit, or play another game like Hearthstone, runescape, minecraft or Simple web browsing on my left screen.

 

Reasons to why i think i should OC:

1. Im going to upgrade soon.

2. I have a second high end computer i can use if this pc fails.

3. Since i have a second computer i wont need to save these parts incase something dies in the future

4. i want higher performance (obvious reason)

5. this is my first time overclock and i want to learn a little more about how it works and how to do it.

 

Thanks!

Reccomend me a motherboard for the microATX xigmatek case! I think a blue color-theme board will work nicely and i think i prefer a Intel Motherboard because my other computer is AMD Fx-8350

 

Sandy Bridge is actually quite the overclocker compared to the newer chips.  Most of SB chips are able to run quite stable @ 4.5Ghz with a pretty good overclock.  

The major downside is that your Motherboard might have a hard time because you can't rly do overclocking like a Z67 board.  So you'll have to overclock with the FSB instead of the CPU directly.  This means that you'll have to adjust the clock of the NB and RAM to compensate the FSB boost. I haven't overclocked a SB chip in a long time and i've never done with a P67 board so this is knowledge from overclocking an H67 board.

You'd be surprised but Ivy Bridge and Haswell don't rly scale well when overclocking like Sandy Bridge, and this means that you can extend the life of the chip for another generation if you want because when broadwell comes out, that might be a game changer. DDR4 and possibly 128-bit processing from the rumor mill.  Many speculate that DDR4 will share the same socket as DDR3 which means it could be possible, and 128-bit processing can be derived from CPU instead of the board, which means easy BIOS update.

Though i know those 2 are a little far fetched but hey...that's the rumors.

To be honest, i didnt quite understand much of what you just said but thanks for sharing. ill have a few more read throughts see what i get XD
