Watercooling is great if you want to keep a 24/7 high overclock and you bench a lot, runs crazy game settings and/or multi-monitors etc.... but if not and your just going to run it modestly with games at stock settings or slightly above, air cooling is just fine. Unless you live near the equator where temps for your ambients would be really hot 24/7, then yeah it would help there too. Water cooling is fun and all until you have a problem and have to dismantle half of it to fix something or rma parts etc.... Also, depending on how you design your loop, it can get pretty expensive to put something effective together, that's why so many people have moved to the all in one coolers, which fall in between air cooling and full fledged water cooling.
