I have an i7 4770K @3.5 and I'm wondering if there's any little thing I can do to make it run faster than it does. Maybe OC? Would I be able to OC a tad bit with the default cooler it has?

More about : 4770k

With the stock cooler? There isn't much you can do with stock cooking with Haswell chips. I would recommend getting a quality aftermarket cooler if you want to overclock.

For an i7 4770k, what's recommended to OC it to? and about how much would I have to spend on the cooler to OC the recommended on a 4770k

Go into your bios and tell me what your vcore reading is. Also, what motherboard and case do you have?

I have the i5 4670K which is the sibling of the i7 4770K and OC's very much the same. I OC mine to 4.5 GHz with the Noctura NH D14 SE 2011. The fans are almost silent at full load! Highly recommended!

The 4770K requires higher voltage than 4670K due to hyperthreading and it runs hotter. A close looped water cooler will likely be necessary for anything over 4.5GHz for a 4770K

ASRock bios actually does''t display this value. Load up CPUZ and tell me the voltage reading at load. Also, do you have a budget in mind for the CPU cooler?

That is too high to be vcore. It is actually the CPU Input voltage. Not sure why it is labeled as vcore... Check the vcore using cpuZ

1.058 V is it called Core Voltage?

It is... you seem to have a fairly decent chip and should be capable of hitting 4.5-4.7GHz with under 1.275V with a sufficient cooling solution.

Pickup one of the following based on your budget:

CPU Cooler: Zalman LQ-310 Liquid CPU Cooler ($39.99 @ NCIX US)

CPU Cooler: NZXT Kraken X60 98.3 CFM Liquid CPU Cooler ($99.99 @ Microcenter)

I'm assuming out of these 2 the most expensive one is the better one. What would I benefit in going with the $100 instead of the $40.
