Water Cooling help/advice

Hey everyone, was looking at investing in a water cooler for my system.. tho my hyper 212 plus does a good job i want a good OC on my 965 BE and my brother need a new cooler and he said hed buy it for like 20 bucks. So that leaves me with about 120 for a water cooler. I figure why not CPU is as ive said an amd 965 be, mobo is asrock 970 extreme 3 am3+ motherboard, my case is the CM HAF 912 (not the advanced one but still holds 2 120s at the top. any help on a good water cooler for this system? best deal for the money, i know the h100i is good but idk about if its that much better than an h80? can anyone possibly give me a ball park as how muhc better my temps would be with watter cool vs air? current max temp is like 44C on full load.

Thanks for the help and reading my long ass post!

Well some air coolers are actually just as good as water coolers. The problem is they are HUGE. 

Water cooling, I'd say just got for the H100i. The dual fan rad size will help coooling.

Closed loop water cooling isn't real water cooling. A Noctua D14 will cool better than an h100 and for cheaper. Save yourself the cash and stick with air unless you plan on getting a full custom loop.

something like an H100i will only cool a few degrees better than a big air cooler, and might end up being noisier aswell, unless you really need those extra few degrees or the look, go for a normal air heatsink, if not get a custom look kit like the XSPC raystorm.
