Im about to overclock my new 4670K and I want to get myself either the h80i or the h100i

Here are my config options for my NZXT H440 case

OPTION 1

H80I mounted in top front fan intake slot as push pull config with both included fans and the other two front slots filled with nzxt stock 120's
Top has twin 120 exhausts and rear has 140 exhaust

OPTION 2

H80i as push pull exhaust at the rear. One top 120 exhaust, three nzxt 120 intakes

OPTION 3

H100i Mounted as push top exhaust with 3 nzxt 120 intake fans and 1 nzxt 140 exhaust fan

OPTION 4

H100i mounted as push pull intake with corsair fans pushing and nzxt fans pulling filling up all 3 front intake slots. (rad interferes with 3'd fan, so I'd cover the lowest fan slot with something to keep ideal pressure) twin top 120 exhaust and nzxt 140 back exhaust

(I am wary of option 4, as it remove the lowest intake, lowering the amount of fresh air (thats not being pulled through a rad) blowing over my GPU - PNY GTX760 OC'd to 1.11 ghz with 2 gigs DDR5)

IMO, get a good air cooler. You are going to spend 60$ more to simply gain 200 MHz additional OC at best. You would have been better in investing in a stronger CPU at that point.

Get the best cooler at around 30$.

For your fan management, intake at front/bottom, outake at back/top. If you can, get rid of the HDD cages at the front of your case. In my case, I am using my 5.25" bay for my storage. I have full airflow.

Im planning to OC at least 1 ghz. stock speed is 3.4 and 3.7 turbo. Want to see if i can get this bad boy up to 4.2-4.5 ghz. therefore, say, a hyper212 evo with noctua fans would still work, but a higher end corsair closed loop liquid cooler would be much better for a more extreme overclock

It's depending on your chip. You might be lucky or not. My 4770k cannot pass 4.2GHz at 1.25V and overheat to the extreme.

You will end up paying 100$ for cooling your cpu for gaining an extra 2-4% CPU performance over a 30$ cooler. Your choice, but I would put that money elsewhere if I were you.

You'd be better off with the larger radiator of the H100 if you're going for extreme overclocking.

I'm also not sure how big your case is but I know for a fact that my H80i doesn't have long enough tubes to be mounted to the front-bottom of my Mid-size case. What I would recommend is mounting it at the top as an intake (to maintain positive pressure.)

Though honestly, I don't know how much I can really recommend this route because with my short time with an H80i, It's not much better than my old air cooler and I'm already feverishly researching my future custom water loop to eventually replace it. I've come to see Closed-loop solutions as more of a stepping stone between air and a proper loop than an actual cooling option for enthusiasts.

This. The ONLY time I ever recommend a closed-loop watercooler is if you absolutely have to have the ability to overclock, but need a very small form factor that can't fit custom watercooling or big air coolers, and you don't care about noise or an increased failure rate.

I've had a custom loop with a 240mm and a 280mm radiator, a CPU block / pump combo, a graphics card block, and a reservoir on outside back of a heavily modified bitfenix prodigy. It wasn't fun, and that's about the smallest you can get custom watercooling in unless you're doing hard tubing and are patient enough to make it work its way around cables and struts to try to make it work in a smaller form.
