Agreed. I have same setup, well similar. 2600k overclocked to 4.7ghz, and 2x gtx 570's with mild overclocks. I got 1 rx360 and 1 120mm rad.
Only time i see a change in temps with the 120mm rad's fans turned on is when Im folding. But for regular use, you will not see any difference except maybe when gaming. 1 360mm rad should be sufficient for your setup.
If you plan on folding on all 3, definately get atleast another 120mm of rad.

Hes saying, it is not recommened to run seperate loops. Unless you really want to spend all that extra money on a second pump and additional radiator. The only way you would ever need a seperate loop is if you fold. And even then you can get away with single loop like i did.
