What RAM do i choose?

Watercooling is an entire different game field. I my self recently switched to watercooling and it wasn't at all cheap. So before jumping into water you need to know that it is not easy to install or to assemble a set. It is also expensive. With that in mind however it is the best cooling performance you can achieve.

Now you have closed circuit units such as the corsair H80. However those will match the performance of top notch aircoolers. Watercooling is viable for enthusiasts that are not afraid to drop 400 at least for cooling alone. But judging by the fact you will install 2GTX 780. It is very viable option for you. Since it will cool those things like no air cooler can.

I am down 40 degree's overall since switching to water. So i am very happy overall. However with water you will need to periodically clean the loop, which means you need to know how to put it in and out, or have a friend ready that knows how to. And u always risk the chance of leaks which are by no means refunded or under warranty. So really Watercooling is enthusiast only thing.

And if u decide to buy COrsair H80 or H100i they are more expensive but ALOT ALOT smaller than top of the line aircoolers which makes them a desirable trait to some. I personally always buy Corsair H coolers. In my opinion and from experience they cool things very well and the noise level is perfectly reasonable and their size is not prohibiting at all. You can easily hook up an H80i to a 120MM fan opening. Unlike the Noctua which let's face it is a GIANT COOLER it's massive. My entire watercooling setup is smaller than that thing.

So the most important price point for Corsair closed circuit watercoolers is. They are very slim and can be installed easily H80i being the slimmest. They cool on parr with air coolers and they are silent and require no maintenance except the occasional dust flush.


Now here is Noctua cooler installed http://img708.imageshack.us/img708/7188/679.jpg

And here is my own computer full liquid cooled.https://fbcdn-sphotos-b-a.akamaihd.net/hphotos-ak-frc1/484776_476538772420797_1640966514_n.jpg.

I assume you can spot the differences.
