Non k haswell i-7 4770

I've recently heard that disabling turbo boost in bios will run all cores rather then just 1 till more are needed....any validity to this? (be gentle im semi-new to this)

I think it runs all cores at the stated speed (usually around 3.6ghz) when needed, whereas with turbo certain cores can be boosted past the stated limit (around 3.9) but only one at a time. There is no real reason to do this unless you are debugging.

Nah, turbo boost just increases core speed, like an occasional overclock. All disabling it does is stop that from happening.

A non K i7 4770 runs all 4 cores at 3.5Ghz with Turbo off. With Turbo on it runs all 4 cores at 3.6Ghz when all 4 cores are loaded, 3.7Ghz when 3 cores are loaded, 3.8Ghz when 2 cores are active and 3.9Ghz when only a single core is active. So just by enabling Turbo you get a free 100Mhz with all 4 cores active. Only disable Turbo when overclocking a K model and even then you can overclock them 2 ways, one by increasing all cores all the time and also by increasing Turbo multiplier so that it scales up higher than stock.
