|"I have never overclocked something before and am a bit scared of this process, is the upside really worth of risking ?"|
There's very little risk. Overclocking hasn't been "dangerous" in a long time. Back in the "old" days, CPUs had no built-in thermal protection so over-overclocking or overheating could fry the CPU. The only thing you risk these days is instability, random shutdowns, or the inability to boot. And if that happens, all you need to do is reset the BIOS & start over.
Your CPU runs at 3.1GHz, 15.5 x 200MHz frequency. Assuming you have DDR3-1333, it's clocked at 6.66 x 200MHz frequency. If you were to simply increase the frequency setting in the BIOS to 210MHz (& not touch anything else), the CPU would run at 3.26GHz & the RAM at 1399MHz. Both should be able to handle that with no problems whatsoever.
"14.4 gb/sec Bandwidth for me looks pretty low"
14.4GB/sec is for the DDR3 version, I'm recommending the GDDR5 version which is 40GB/sec. See the 2nd link in response #8.
