You will game better if you spent that $100-$200 on a stronger graphics card and forget about liquid cooling.
If you insist, here is a recent article on it:http://www.anandtech.com/show/7363/the-neophytes-custom-liquid-cooling-guide-how-to-why-to-what-to-expect
Well the reason i want liquid cooling is cause i wanted my comp to run cold, and i dislike the fact my comp collects a lot of dust. And i'm only using this graphic card for now, so i can build a water cooling system . I will upgrade my GPU to better ones later on. I feel like these graphic card will be enough for the time being.
