LLC stabilizes your CPU voltage (comparing what you set in the BIOS against what CPU-Z shows under load during a stress test)—but because of that, it also bumps up your temps slightly. You really need to play around with it and test to find that sweet spot, especially with high-end boards that offer different stages like high, medium, etc.
Generally speaking, it helps, but if the voltage isn't dropping, then LLC isn't doing much for you. For example, here is a rare case where LLC didn't help at all:

You might actually see some benefits in those strictly single-threaded games that don't play nice with AMD, even with that card (like World of Tanks, Rome TW, etc.). Since you picked up that CPU, motherboard, and cooler, it would be a shame not to push it past 4GHz—even by a few hundred MHz. Those newer Visheras (8320e, 8370, 8370e) seem to be absolute beasts when it comes to overclocking (they require less voltage for a given clock speed, which means even better temps).
My FX8320E holds 4.1 GHz at 1.2vcore.
For an FX8370, I need 1.39vcore for 4.9GHz, but it holds 4.4 at 1.2625v.

As for coolers—honestly, forget liquid cooling; air coolers are much more cost-effective. That’s the other issue with the cooler you bought—it isn't a great value. It’s more expensive than a Noctua NH-D14, yet it performs worse.
