Im thinking about going into watercooling. My budget is about 150$, and i have an asus pk5 pro, q9450, antec 900 etc. I was wondering if i should either get watercooling, or, after noticing that quality watercooling sets are pretty expensive, im wondering if i should get one of 2 other things. The first is a new motherboard that has sli, and the second is more ram amd a sound card. counld i get any help on this? If so, thanks alot.
