Sorry if this is a really obvious answer question, but i'm wondering if you are able to OC a non OC edition GPU / CPU, i'll be getting a HD 7870. i5 3570.
However, a CPU that isn't unlocked can't be overclocked without essentially ruining the rest of the system - get the "k" edition.
Not exactly true. Because the i5's/i7's have Turbo, you're able to raise the Turbo multipliers by 4 "bins" each to achieve a small OC, even on a non-K CPU.

You can overclock non "K" Sandy and Ivy Bridge i5 and i7 processors 4 bins over stock via Turbo. That means an extra 400Mhz.
