New Build Liquid Cooling help

[Lynx33]

Hello,

I have chosen most of the components for a new build, here's what I have so far:

CPU:

Intel i5 3570K

Motherboard:

MSI z77 MPower

Graphics Card:

EVGA GTX 670 4 gb/ GTX 680 2 gb (suggestions?)

Case:

Corsair Obsidian 650 D

Memory:

GSkill Sniper 16 GB 1600Mhz 4 modules

Storage:

Corsair GS 360GB Force Series

PSU:

???
I want to liquid cool the CPU and GPU, so I need help picking good water blocks, fittings, tube sizes it's my first liquid cooled system. Also if you think any of the components are too much, or have suggestions for what might work better please say I am not attached to any of them. This system will be used for gaming, I plan to use either a 2560x1440 27 inch 60 hz monitor or a 1920x1080 24 inch 120 hz monitor. Thanks!

I would dump the 8GB for gaming. Also, for higher resolutions I believe that the AMD 7950 or 7970 would perform much better.

How much do you have to spend on the PSU?

 

[Lynx33]

Which 8 GB? And for the PSU I'll pay whatever I have to in order for the components to function properly. I'll look into the 7970

Sorry, I meant you only really need 8GB of RAM for gaming. The power supply depends on whether or not you want to run more than one video card in the future.

Yes I am planning to, also should I go for the 670 4 gb or 680 2 gb?

I would go for the 670, but the 4GB is pointless if you are running 1 1080p monitor.
