Overclocking i7 3820

I'm currenlty in the process of getting parts for my gaming and mild editing PC. I'm going fairly high end and I was wondering if you could overclock an intel i7 3820 CPU with the performance option in the uefi bios of an Asus p9x79 Pro motherboard. If so I would appreciate to know how much of an overclock I would get from it. I have already purchased a nice liquid cooler so cooling shouldn't be a problem.
