If you enable multi core enhancement, it automatically puts the turbo multiplier to 39 under any load situation, regardless of how many cores are being utilized.
So basically it results in faster performance, but the offside is a little more heat and power consumption. You should be overclocking anyway past the highest turbo frequency, even at stock voltage you should be able to achieve higher than the highest turbo multi (most 3770ks get to ~4.2ghz give or take 200mhz on stock voltage). It's up to you, I would keep it enabled if you're at stock but you should be overclocking anyway so once overclocking comes into account it doesn't matter.
LLC controls vdroop under load, which for overclocking typically you want a more steady voltage rather than a drop off. I recommend setting it to ultra high on Asus, but again this is irrelevant compared to multi core enhancement.
