I'm wondering whether I should get an i5 3550 or an i5 3570k. The difference is $10 but I would need to buy a Z77 board if I did get the 3570K. I just want to know if the overclocking something as awesome as an Ivy Bridge i5 really makes a difference or not? I'm kind of scared of overclocking too but their are guides to help me. Will I even need to overclock?
