i5 3470 or 3570

[vald95]

I'm currently off-state so I'm writing in english. I intend to buy a new PC and all my specs are ready. I just have a question about the proccessor , I saw a lot of pc's people made here + on the "recommended PCs list" that u use the i5 3570 a lot more than the 3470, whats so different there? Especially in a combo with GTX 570 like I'm getting..

I mean, is 3470 really falls back in a substantial matter because its only like 20$ cheaper than the 3570

(btw I dont mean the K versions, I wouldnt do an OC either way)
