Personally if money is an issue go for AMD.. You get more for your money. Simple.
I disagree with CHKN, in this day and age you don't need to know anything about liquid cooling to buy and install one. I just bought the Corsair H70, it is a completely seeled unit. When it comes, simply take it out the box, screw the fans and radiator to the case. Plug in the fan power leads, and screw down the heat exchange onto the processor. 20 mintue job. Cost is about $135, but you can get it cheaper in the States. You would need a big case, but if your case is small then get it's smaller brother the H50.
a noctua keep the cpu cooler than a h70
I had an H70 for a couple of weeks to test it....true is you have the same temps like a real good aircooled system
btw I am running a i5 750 at 4 Ghz with a Prolimatech Mega Shadow Apache Edition...
the noctua is at the same level like mine
also true is...you will get in trouble with the rest of the system if you dont have enough airflow in your case
I had my other temps going up while the H70 was installed
