How many GHZ can this CPU cooler get me up to?

I'd say easily (although that really depends on whether you got lucky with the silicon lottery), hell I can get 4.2 (albeit on a 3570k) easily without any other tweaks to anything simply on a CM Hyper 212 Evo.

What about a Zalman LQ310 or Antec's Kuhler 650?
 


those are above my budget. IS OCing hard?
 
Well i want an h100i....heres the story in a short way. Im picky. I want an H100i. I have 333$ BUT I CANT use all of it cause i got to save for shipping cause shipping to UAE is expensive..AMAZON only. I am getting a S2440l dell monitor for 200$ . If i want, i could get a 150$ monitor 1080p and get an SSD or H100i...First of all, should i stick with the 200$ monitor? If not, which should i get? H100i or SSD? (120GB EVO)
 
hard to say, i would rather goo with better monitor and upgrade cpu cooler next month or later, in terms of upgrading ssd or going for h100i- ssd will give a huge boost in general performance, file transefer,boot times, load times so on, while the cooler will allow you to oc your cpu pretty far giving a biger performance imrpovement in everything that cpu bound
